Stripe Sync Engine, how to implement custom schemas?

For example, if I want to use this Stripe version 2025-03-31.basil, I know I can modify the migrations, install an specific version of stripe, and change the stripeApiVersion.

But it's not very clear how I can update the table schemas. I reviewed the code, and it doesn't seem possible.


For example, in the version I want to use, some fields were moved from the Subscription schema to SubscriptionItem.


So what can I do?

That's just an example; there may be more cases in Stripe's changelog.
