How to populate a list of predefined strings based on another field in the same document

Hey everyone,
I'm wondering if there is a way to populate a list of predefined strings based on the value of another field in the same document?

Basically what I'm hoping the achieve is this. I have a
document that references
and the
can conditionally have sub-categories which are just added as string tags. I was hoping to be able to add a
and be able to give it a sub-category based on the ones already defined in the
. I've been able to get it so the editor can just type in a category and it will be invalid unless it matches one already defined in the sub-categories field but this seems a bit hacky. Any advice on how best to achieve this? Perhaps custom input component?

Nevermind. Figured out a solution myself using a custom input component as suspected 🙂
