Multi-tenanted Remote Schema with varying remote URLs

[binary64]

I am trying to wrap my legacy MySQL databases with Hasura. I have 1 tenant per MySQL database (these are on different servers around the world).

So far I have a Prisma server sitting in front of each MySQL database. This gives me 1 graphql URL per tenant. All URLs will have the same schema.

In Hasura, this works if I set the "Remote Schema URL" to 1 tenant at a time.

The correct Remote Schema URL is actually embedded inside my JWT authorization token given to Hasura. Ideally I want to specify this as my Remote Schema URL: {authorization.jwt.my_remote_url} or something.

Or do you have any other ideas?
