Paint brush path - use for linking object motion?

[EditingBob]

Searching everywhere and can't find if it's possible to link a paint brush path to another object's motion parameters.  I'm drawing with the brush tool to create a reveal effect, and would like to use the brush path to drive an animated pen.

I need to fix my name!  It's Bob Woodhead... appreciate all the answers you've given folks over the years, Kevin.   Anyway, yup, solution was to just go back to Motion.  The process is super easy and close to perfect alignment.   Sometimes some segments of the motion path don't link perfectly temporally, but not enough to be a problem.  But the good thing is there's zero mucking about, just apply brush path as a motion path for the hand, and done.   I admit to often using the approach that works quickly instead of elegantly.

I can confirm this is not yet fixed. Pasting from paint path to position doesn't align in time - even stretching start and end keyframes to match the paint tool doesn't fix the timing.

Still not fixed in 2020.

If we could just change the interpolation it would be an easy solution.

BTW, I'm not sure if Paint and Stick would help you out at all. Worth checking out
