File specific toolboxes

I'm a Div. 8 Estimator / PM. I regularly have to take-off door counts from plans. I will make a tool set w/ the door tags from the door schedule, so that I can mark up the openings. My question is, has anyone made toolboxes that are specific to a given file? The reason I ask, is that the tags / door types are never the same from one set of plans to another. I would like to be able to have toolboxes that are specific to a given set of plans.

Also, is there an easier way to change the properties of a markup rather than just placing an instance on a sheet, modifying the properties, and then adding it to a toolbox?
