Moving and renaming newly imported assets

I work at a small college tv studio and am trying to deploy a Final Cut Server setup. One of the requirements of our setup is to have an actual file structure for our footage so that it is not all thrown into one folder by FCS.

I'm very new to FCS, but I understand how the system works from a general standpoint. Here's what I'm trying to do:

1) Import assets into FCS using the client app, choosing a category (like "B-Roll") in a metadata field or lookup
2) Setting up an automation to Move the asset to a folder called B-Roll on the device.
3) Rename the asset filename based on other metadata fields (e.g. "CampusExterior Library030420111510.mov")

I'm pretty sure I could do 1 & 2 by simply setting up an Automation for each category to Copy the asset to that folder and then Delete the original, but I haven't been able to figure out how to accomplish #3.

Any help would be greatly appreciated!

Also, I understand that it's best to have FCS manage the files itself, and I will NOT be allowing anyone Finder access to the structure. I want the file structure their for safety purposes (FCS server dies, user readable backups of footage).
