Handle group collections

[echoti]

For the ones who handles their comments / messages in group collections, it could very handy to be able to configure a such type of path.
Thank you very much for your consideration

Hi @echoti, could you clarify what you mean by a group collection? We also welcome contributions, if you're interested in implementing support for your use case.

"A collection group consists of all collections with the same ID" (https://firebase.google.com/docs/firestore/query-data/queries#collection-group-query)

To give a concrete example, I have a "discussions" collection where every document define a "messages" property which is a sub-collection (https://firebase.google.com/docs/firestore/manage-data/structure-data#subcollections). The documents I want to analyze don't belong to a top level collection.
