Terraform API Management API Policy - All APIs

Question

I'm aware that it's possible to create an API Management API Policy using terraform by adding the following two resources:API Management API and API Management API Policy. The issue is that I want to add the policy for "All APIs" (seen in image)

and not for a specific route. I do not see a way to do that through Terraform. I am able to do it through Powershell though. So that leaves me with three thoughts:

1. I should just do it through powershell
2. I should NOT be using the "All APIs" option in the UI and instead should always explicitly assign the policy to each route. (kind of a pain since connecting Function Apps to APIM is going to auto generate APIs for me)
3. I'm missing something and this can be done through Terraform.

I'm looking for an answer to point 3, and open to opinions on point 2.

Thanks
