I am getting deeper into sheet sets and finding a number of features that I thought would be there but aren't.

This request is for custom properties per sub-set. I could see multiple uses for this but the one that keyed me into it is setting total number of sheets (a custom property for now). As an example, I setup a sub-set for small scale (11x17 @ 1/8") and another for large scale (24x36 @ 1/4"). One of my detail sheets is 2 sheets worth of details on 11x17 and one sheet of details on 24x36, hence, my 24x36 sheet subset is one sheet short of my 11x17 but I have no way to make the total number of sheets different.

One of my other requests is sheet xx of yy which I think should be able to be set to "per subset" which would cover this request but I am sure there are many other custom properties that would be nice per subset.
