Comment 11 for bug 1154131

We could add a textctrl into the Sheet dialog ("Start number" or something) and write it out within the sheet name:

F0 "PSU|300" 50

When reading we'd separate them and use the number if found, otherwise defaulting to our existing numbering algorithm.

This doesn't "really" change the file format; external tools might display the name with the number attached, but that wouldn't really be bad (and better than not displaying it at all).

This one has enough people interested in it that I'd hate to have to wait till 6.0....

Thoughts?
