Network Folder Scanning : Manual scan of subbranch, or different update rates for subfolders

[meteorquake]

Network folder scanning is a little temporamental (it is on 'monitor changes').
Often you do something and Everything instantly reflects it. But sometimes it appears to be very slack in doing so.
I mentioned once before the idea of Everything noting your file action performed in everything to do a definite immediate update, anyone doing file operations mostly or entirely in Everything will find that useful - I imagine that's under consideration if it's viable (perhaps it already is but needs improving?)
So my question is, is there a way to force a rescan of a selected branch within a network folder that's indexed, as usually one is working on a particular area, and rescanning the entire folder is overkill, especially where large, when just a small portion needs more regular update.
Perhaps subportions can be designated with a different update rate under the Folders tab? you could add the folder with a different rescan setting, and Everything could recognise it is a subfolder of one of the other Folders entered and so not duplicate the indexing, but adopt different scanning timings for the designated branches.
Or - and perhaps this is the best course - Everything could note the folders getting changed (either by actions noted within Everything or external updates spotted during a scan) and intelligently rescan at a faster rate those branches, which is a variant on the tracking the file actions you do, which would cover the possibility of some actions being performed outside of Everything.
