Sketching Basics: wake up / select geometry from another plane while sketching

Hi there,
Basic SW to OS transformation question:
While in SW(and other CAD) I can select and directly constrain geometry from other than sketching plane when in normal view it will not work the same in Onshape.
However I can constrain in Onshape it afterwards either in normal view or also "free" view.
Is there any hidden key to make non-sketch-plane geometry selectable/constrainable while sketching?

Sketch constraints work with geometry not in the sketch plane. For example, Coincident in the animation below. I also use Pierce a lot. You can also use the Use and Intersection tools to bring geometry into the sketch plane.
Dear Matt,
Thanks for your ideas. I'm aware of the constraining options after sketching or also the "use" tool.
But what I mean is having active snapping to other geometry offset to sketch plane while sketching the line.
If your looking for a line between planes, You can use the 3d fit spline after sketch is completed. It won't close the sketch area but can be very useful as a guide. 3d fit spine with 2 inputs and no other adjustments behaves like a line.
@Urs_Egger_REACT I'm also looking for this function. While placing a new line the constraints are not placed on external references. I have to finish placing the line and then add the constraints afterwards.
I think this is an unnescessary step and hope it can be done in one step in future.
I've been doing this for some tome as a one step operation. Not sure why it does not work for you. Unless you're trying to do the 3d spline inside the 2d sketch. I finish the sketch then add splines.
I just tried it gain. When the geometry I want to pin my line to is not on the same plane as my sketch i can not snap the points of a line directly to it. I have to place the points of the line and then add the constrain to the geometry in front or behind the plane afterwards. This also counts for draging the line after placing it. It won't snap to the geometry infront or behind the plane.
The 2d fit spline mentioned earlier is not done in a sketch.
Can you post a link to your document?
I think @Matt_Shields has shown the only solution there is at the moment. i hope it will be solved in future.
