Featurescript UI Question

Hello everyone.

This is my first featurescript.

I am attempting to expand on @jeff_brown304 's Camel project, by making an improved CAM drill tool. The intent is to have the user select a cylindrical hole surface, and subsequently unhide portions of the UI that correspond to different features that the hole may have. For example, if the hole is countersunk, a "countersink tool" selection box will show up, along with a dropdown for unique feeds & speeds, etc.

I have figured out how to pull the holeType attribute, and assign it to a boolean variable, but I am now realizing that this cannot be brought back to the precondition.

        //if(????) I would like to toggle the below feature based on the presence of a countersink attribute
        {
            annotation { "Name" : "Countersink Tool", "Filter" : BodyType.COMPOSITE, "MaxNumberOfPicks" : 1 }
            definition.countersinkTool is Query;
            
        }
    }
        
  {
        var selections = evaluateQuery(context, definition.selectedHoles);
        
        for (var face in selections) 
        {
            var allAttributes = getAttributes(context, { "entities" : face });
            var foundHoleData = false;
            var counterSunk = false;
            var counterBored = false;

            for (var attr in allAttributes)
            {
                if (attr.holeType == HoleStyle.C_SINK)
                { counterSunk = true; }
                
                if (attr.holeType == HoleStyle.C_BORE)
                { counterBored = true; }
                
                
                if (attr.holeDiameter != undefined)
                {
                    foundHoleData = true;
                    
                    if (attr.isTappedHole)
                        println("Major Diameter " ~ attr.majorDiameter ~ " Pitch: " ~ attr.threadPitch);
                     else {
                        println("Simple Hole: " ~ attr.holeDiameter);
                    }
                }
            }

            if (!foundHoleData)
            {
                debug(context, face, DebugColor.RED);
                throw regenError("Feed me a hole" );
            }
        }

I am looking for a way to get attributes of a feature selected in the precondition, back into the precondition.

Here's the document: https://cad.onshape.com/documents/927a40c416a1bc927796df37/w/3800a45cf3b68f0191925f6d/e/a85f5e7c93463861124927d4

Additionally, the way I have the "holes to drill" menu set up, allows selection of incorrect geometry, (partial radiuses and cylindrical extrusions) and sends an error message if no hole data is found. I would like to somehow disallow highlighting and selection of everything but cylindrical holes parallel to the machine setup Z axis, and allow simple circular extrusions with no attached hole data.

        annotation { "Name" : "Holes to Drill", "Filter" : GeometryType.CYLINDER && EntityType.FACE }
        definition.selectedHoles is Query;

I'd appreciate any help or pointers.
