Key farm question

So I am in a server that is semi active and we getting into key farming as much as possible, we have around 6000 claimed characters on the WA roulette.

I wanted to know if there is any way I can change my DL so I can include as many claimed characters as I can so I can then use Persr 4 to further lower the overall pool of characters I can get in a pull. I wasn't able to find the best bundles to disable since I can't find anywhere a command that shows both bundles and the amount of owned characters they have. Can someone help out or is it just not feasible?
