Read group counts from main site when automatching scrambles on scrambles matcher

[Sixstringcal]

When generating scrambles, I like to overgenerate a lot in case the absolute worst happens (two extra groups per round of each event). When I submit, this becomes annoying because I have to drag (and sometimes the drag and drop just breaks and I have to refresh the page and go through the process again: see #7220

It would be great if it could read the number of groups I have per round per event that I set in the main site and populate only A, B, C if I have 3. Obviously, if something happens like an extra round is used, but it's maybe set F from round 1 I'll have to manually do that, but cases like that come up less often, and the general case would make my life measurably improve.

This should probably be an issue on the scrambles matcher repository?

Oh my bad. I looked for it briefly, but couldn't find it and found the linked issue #7220 on this repository, so I figured it was in the same repository. My bad.
