The new mass-check cub mutations feature is really exciting, but its all-or-nothing approach can make it much more expensive to check cubs than it needs to be.

Just as cubs are sorted by cave for the individual mutation checks, I think it would be useful to be able to mass check cubs in specific caves. This way, if you have cubs that you don't want to check for AMPs (for example, if you're already planning to keep them until they're adults), you can sequester the cubs you do want to check in a specific cave and go to town.

Maybe there could be a dropdown menu added to the mass checking space, where choosing a cave would then update the SB/GB cost option (similar to making applicators, where the available marking slots update upon choosing individual lions).
