Indexes using relationship

Hello there ! :appwritecheers:

I was playing around with Database, Collections & Documents and I found an "issue" which isn't realy an issue but a missing feature I guess.

I have a collection "Brand(name: String)" and another one "Model(name: String, brand: Brand[ManyToOne]"

I've set a Unique index on brand.name and I wanted to add a index on (model.name, model.brand) but it seems that we can't use Relationship in Indexes.

Am I missing something ? :appwritebow:
