How to align points and tangents on 2 different masks?

[Jay Mueller]

How about using guides? Place guide(s) to point/tangent and then set additional mask to those guides.

..sure Dave, heres a near exact description:
imagine mountains1 at the horizon, and another line of mountains2 just infront of it closer to the viewer.
Both mountains have masks along their tops and bases, and what i need to do is align the mountainTop1 points and tangents on mask1, with the mountainTop2 mask2 points and tangents.(screenshot if needed)

ie: need to align a mask point position&tangent with that of a different mask point, one at a time or all at once,

Thanks again,
J

If you are repeating masks across several layers, you might find it easier to use track mattes instead:
