Editing links within backlinks

Hi. I’ve been going through some backlinks ([[teaching]]) trying to group them into subsets, e.g. [[teaching/prep]] [[teaching/materials]]. I can’t seem to do this in the backlinks, but when I go to the relevant pages I can see that the file links have in fact been changed. Would it be possible to allow editing of links within backlinks? (just as the text itself is editable)? Thanks.
