I have a couple imported 2d line sketched I used to create parts using extrude, etc.  I would like for the 2 sketches to remain displayed in their "un-absorbed" positions at the top of the tree.  Otherwise I have to go poking down thru all of the features until I find the first one to use each of the sketches.  I know I can roll back and split them apart, but that isn't what I want.  I want these 2 sketches to always stay displayed in their original position.  Is this possible?
