Yes, exactly. Is this a XOR rather than a OR?
Yes, XOR. You want to get EITHER the A squad, (exclusively) OR two B squads.
A simple OR, would allow both
So, did you try my method?
If so it could be done I suppose - you will have set different cumulative squad requirements in the two squads.
The A, must have cumulative of 1 with the B.
The B, must have cumulative of 2 with the A.
I have not tried it, though.
... But I am afraid it will not work. Because if you get one B squad, the A may still be available.
If that is the case, also ADD in A squad requirements the required_squad , with min_count 0 and squad_name the B.
