That's a cool bit of effort you've done.
I've been working on an updated Version of the unitattributes.xls, and currently have almost all of the independent unit stats listed, and I can probably lift a lot of the summonables from the original. I've made it sortable by availability (where can you get them), command capability, sacredness, unit_ID, name and a lot of other things, but it's nowhere near ready yet. More news when it gets nearer completion.
