"i have done a couple bad things"
blocked on my side project because i have no idea how to design this interface 
im absolutely a design dilettante, is it an internal interface or a user-facing one?
user-facing. the problem i am trying to solve is essentially that i am generating a spreadsheet of mappings that a user to edit, but the number of rows can multiply combinatorially based on user-specified modifiers, and i'm not sure how to handle this in a way that doesn't blow up the spreadsheet.
based on this description alone i'm feeling like adding a more specified layer on top of the rather generic thing i am currently calling "modifier" right now could help; the internal representation is too general to expose in a structured way! might post about this more later if i can nail down the problem but even thinking through it this much was helpful enough for me to feel unblocked haha
oooh, i'm glad to have accidentally helped already! i'd be interested in reading more for what that's worth :)
