@OliverE if you are managing large sheet sets then the attached may help.
I put it together back in 2012 for a particular project I was working on that had a lot of sheet layouts and I was fed up with updating each title block whenever the set was revised. I was trying to learn vba at the time and thought it would be a good little project to learn. It is simply an attribute editor but it edits all instances of the block to match the values given. Useful if just revising a sheet set. I use it on an almost daily basis now. Be warned though, it edits all instances of the block to match your values, not just one! It will work with any block, not just title blocks. I kept meaning to add an option to prefix or append a value but just never found time to learn how to do it.
Admittedly I've never tried SSM though so maybe that does the job better, but the attached lisp and dvb file work fine for me. It's a bit rough as I never found time to tidy it up (I could never get the titles of the columns to work properly either so they are missing), but it's perfectly functional. You'll need to update your support file paths to the folder that the .dvb is saved in, and probably put it to the top of the support folders as I find it doesn't work unless the path is first in the list. The .lsp file just sets up the command and loads the .dvb file.
When loaded, type satt at the command line and you will be met with a blank window, you can use the pull down to select your block or use the button at top right to select it. Your attributes will then be loaded. You can edit an attribute as you would in the usual way using the box at the bottom. Attributes that have been edited are given a "*" next to them. Any attributes that have differing values across the blocks are labelled as *varies*. Any attribute value labelled as *varies* will keep it's current value unless you edit the value *varies*, which will then overwrite it for all of those attributes.
If anyone with more knowledge wants to upgrade this then be my guest, just send me a copy of the improved version 🐵
