Hi @Anonymous,
I mocked up a Sheet Set that links to 5 drawings that each have one layout. I used xref to link your titleblock to each layout. Then I inserted a block that consisted of attributes. Each attribute is a field linked to the Sheetset properties. Most of the properties I created as Custom Properties.
You can explore this sample and see how to adjust all the fields right the Sheet Set manager window. Some of the properties are specific to each sheet such as the drawing number and other properties are part of the whole sheetset such as the Customer Name.
You might find navigating your drawings is easier using the sheet set manager too.
Just for fun I also Rt-clicked on the top level of the sheet set and created a Sheet list table (Index) too that is easily updatable.
I hope this gets you started.
