Execute function "on before create" a document in a collection

[dj-fiorex]

Hello everyone,

I recently transitioned from Firebase to AppWrite and I'm trying to find a way to trigger a function before a document is created in a collection. Specifically, I want to add certain properties to a new document before it's actually created in the collection. Is there a mechanism in AppWrite for achieving this?

I have already reviewed the documentation and found the databases.*.collections.*.create event, but it triggers after the document has been created. I need to add required, calculated properties to ensure successful write operations.

Thank you for your assistance!
