Inserting a separator in Action Bar drop-down

First - happy 2010 to all.

I’m trying to improve the look-and-feel of my modification to the C&S application. One thing I have added is a lot of Agents and I am trying to group them something other than alphbetically. I know that there can be a one-level grouping with the backslash, but I really would like to have something deeper. If I can separate, and maintain some order between the separators, that would be good.

One more thing - I am trying to do this with Agents, not with view Actions, because these functions have to be available wherever the user is - I don’t want to have to modify the design of every View and Folder!

So, anyone can help me - please!
