I used to have a formula setup in Dr Neau's tourney manager that changed the number of payouts based on buyins, and in a rebuy tournament based on buyins + rebuys. I can't remember exactly, but it had variables in it based on buyins and rebuys.I also use BlindsUp app, it doesn't do a lot of things correctly but it does allow you to post payouts in any amount you want. If you let the app figure pay outs by % it will use cents, so I input the payouts manually for a fixed amount, looks like what you are doing on your board?
What do you want it to do that it doesn't?
So for example, if there were <14 players, pay top 3 finishers at 50%, 30%, 20%. If number of players equals 14 or higher, change it so 4th place gets payout equal to buyin, remaining amount split up 50%, 30%, 20%...
Or if buyins + rebuys > = x... you could pay 4 places...
basically something like that. I don't remember the exact setup of the numbers for payouts.
Blindsup couldn't do that kind of formula based payout calculations. It actually seemed pretty buggy with just regular payout setup.
The creator said it would be able to handle all this in the new version, but that's pretty much vaporware.
