When I change the size of the underlining part (example increase the height)
then I have to move my clones/extrusions by hand too:
A nice property of a sketch was that it moves with the underlying face.
When I modify the underlying geometry the sketch/feature moves accoring to the connected external geometry
Is there something like the "Copy Location Constraint" in blender or another trick?
The general answer is probably the Assembly wb when the branch is generally available.
There are various ways for specific situations, like if the layout has some sort of regular spacing to the layout, you can use Draft Arrays of Arrays e.g. polar array of lineal array etc., or a draft Path Array
If there is nothing regular about placements then at least you can multi-select then go to edit menu and run Placement tool but tick relative mode, then you can for example move them all 10mm in some direction manually.
Or in the Part wb you can create a compound or a fuse of a group of objects then their placement can be set manually for the whole group while retaining their individual local relative placement.
