independent points from copy geometry

[Hope]

Good morning.
often I happen to insert copies geometry into the part I'm modeling.
on these copies geometry then create points I use for modeling.
once finished the mixed piece "manually" the coordinates of those points and redefine them compared to a csys so that you can remove the geometry copies created initially by clearing the part from any external reference.
I would like to avoid measuring each time the coordinates of all points. Is there a faster way to clear them from copied geometries?

Thank you all.

This is a video in which it is explained how to make an independent surface copied together by another component : I hope that the same principle applies to points
