Re-use / copy a sketch + retain constraints

POC

Hi,
I have random hole patterns that need to be countersunk on both faces of the part,. is there a way to use a single sketch for both sets of holes?  

Thanks.

Maybe create a single hole (with the countersinks) as a feature, then pattern that with a few regular patterns, and then delete the holes you don’t want with delete face?

Alternately, you could make through holes with that sketch and then add countersinks with the selection fillet custom feature (which also can make chamfers).

I'm sure there are several other options that I’m not thinking of.

Thanks for the response S1mon 
What you've suggested will work & if I'm 3D printing the parts I use similar technique (normally boolean subtract) but I like to use the automated hole callout table on my cnc'd parts so the drawings are correct. AFAIK what I've asked for in my initial mail isn't possible.

You can also use the Fill Pattern custom feature, but I don't know a way to get the a countersink on the second end of the hole feature other than adding a chamfer.

Here's a simple example: https://cad.onshape.com/documents/86cd2d6cc3e920442c7ae169/v/4fae4df79c1cd62d05e0895f/e/eaf176b233dde51a7a91e53b

Thank you - I didn't know about that technique.. I'll evaluate it further - Thanks again.
