Separate interactable scaling for void seeds vs chests, etc.

Is your feature request related to a problem? Please describe.
Interactable credit lets the number of void seeds on a map vary wildly.

Describe the solution you'd like
I would like a way, if possible, to specify the number of void seeds (or a separate "void credits") to tweak how often void seeds spawn. For example, I'd like a normal interactable credit of, say, 10. But I'd also like 1-2 void seeds per stage only. With a credit of 10, I can get 10 void seeds + other things, which is nigh unplayable (especially if you spawn in 3 fields on a small stage).

Describe alternatives you've considered
Unsure.

Additional context
None.
