The challenge is that the ability to selectively work on a subset of files shared on a network drive sounds a lot like what our network product is for. This wasn't explicitly removed for any reason... it's just that when we had to reimplement this feature due to our database migration we only solved for the expected scenario of repairing a database.
That being said, I am looking into alternative ways of accomplishing this and we are very actively discussing the requests.
As one alternate suggestion.. you could import every file, and then rely on homebase filters to limit what people have to work with. For example, you could filter by Preparer, FIle Name or Client Status, for example. I can appreciate though that wouldn't work if who works on what is based on something that doesn't show up in a column.
