Sheet Sets - Easy way to set up Client title blocks to use sheet sets

Every client seems to have their own title block requirements.  Is there an easy way to set up Sheet Set custom properties so that I can put them into the titleblock block as fields.  Some properties are common across drawings (eg title, chainage references) and some are specific to the drawing (eg revision, checker, etc).  It seems you need to manually enter the list of custom properties and then populate them individually. It seems too tedious that I think I must be doing something wrong?

Thinking forward, is there an easy way to update certain fields across all of the drawings.  For instance, suppose I want to rev up all of a drawing set (or just the vast majority of them), is there an easier way than clicking through each one.

My wishlist would be for a tabular arrangement with a cut and paste to Excel.
