I take them one league at a time, first f.e. the bundesliga, 3 matches is 9 results, update the options to 9, then type in draw, copy paste this over all the draw lines.
The I add the teams for the matches I picked and then indeed remember the odds per match.
Or, if I set it up at work, I have two screens so then I don't need to remember it.
And the do the same for the other league, just updated the number off odds every time, and the draw is remembered so the copy paste is done fast.
And for CL, I just pick all matches/day. The the draw is copy/pasted even faster.
