ZIA URL category - known only after apply

[carsten-re]

Hi,
I'm kindly asking if someone already have a solution for this:
I want to create dynamically URL categories where the content is coming from a CSV file.
My Terraform code is already working at a very basic level, but I my challenge is the "category_id" value in the planning phase.
The resource is created in a for_each loop.
My "bad" workaround is, that the key value of this resource is the "configured_name". The downside is, that when this value in CSV file is changed, Terraform will destroy it...

My goal would be to somehow get the next available ID (like CUSTOM_07) when Terraform is in planning phase.

Any idea how to solve this?
