If I search for a missing file and find it, LR manages to find any others in the same location.
Could a similar process not apply to missing folders. I have a parent folder with approx 30 sub-folders all of which I wish to rename. I prefer to do this outside LR and then re-connect inside LR. I know that the normal advice is not to do this, but I find this is less of a pain than doing it all inside LR.
As every single file inside each of the 30 folders has the same name as before, surely it would be feasible for LR to check for any missing folders in the parent folder, then scan for the relevant files in a similar way to the current behaviour for missing files.
Currently I have to manually re-find each of the 30 folders.
