Exclude files/folders from syncronization

Good morning.

I would like to request the ability to exclude files and/or folders from the synchronization process, as I'm sure other users here would appreciate the same ability.

I have four folders on the server that I work on daily, that have over 400 files and 317 folders that only change once a year.

If there is an ability to mark that parent folder as Exempt that would be awesome! That would cut down almost three minutes of scanning each time I run the sync (quite a few times a day).

Thanks!
