Is there a geometry node like 'Group input' that gives the original topology of the object without any previous modifiers?

It's for a voronoi pattern. For most shapes it is needed to first do a 'Remesh' modifier to make the holes. After making the holes in the object, I snap the points back to the original shape. Now I have copied the original shape to do it, bud copying each object makes a mess.

Using copied object to snap to: enter image description here

Remesh modifier, no geometry nodes: enter image description here

Snapping to the same object (who has the Remesh modifier): enter image description here
