[#1]

After all these years, I FINALLY decided to get my head around the Sheet Set Manager (kudos to Kate Morrical's video series).

I understand the need to create custom properties, and I can see that you can either "add" or "delete" custom properties, but is there any way to CHANGE the property after it's been defined?

For example, if I create a custom property complete with a default value, but discover later that I made a spelling mistake (eg. "Darwn By" instead of "Drawn By"), is there any way to MODIFY it?

[#2]

you can change the value, but not the label. I would guess that the thinking is that the custom property _may_ already be referenced by a field in a drawing, and changing the label would break the linkage. 

I don't know if that's an accurate guess on my part or not: .dst files are not readable as text or xml.  Check with the SSM Editor on jtbworld.com - if anyone can do it, Jimmy Bergmark can..
