how to use collection name instead of collection ID to createDocument or listDocuments functions ?

i'm making a web app but whenever i get documents i have to give collection ID, when app will grow with tons of collections it will be difficult to manage all the IDs, how to use collection name instead of collection ID to createDocument or listDocuments functions ?

first off, do you need tons of collections? Maybe there's a better way to organize your data?

Secondly, how about you use the name as ID? You won't be able to use name...it has to be ID because it needs to be unique

the issue is resolved

thanks for your help
