Hi Ferric. Welcome to the forum.
EDIT
Ok, my bad, I only realized after the fact that this is not quite what you are asking for.
So, as a meanwhile solution, here is how I do it (somewhat):
Design yourself a tag, something like [=LocTag], and drop it at points of interest.
You can have that tag in a document in your project bookmarks for quick access, where to copy-paste it from.
After that, all you have to do is search for it in the document of interest, using Edit / Find / Find...
You can remove those tags at compile either via replacement, or, if you design your tag with a character attributes style, via the styles panel of your compile format.
For the more elaborate version of this idea, see:
