Is it possible to charge multiple delivery fees (using Recharge Subscriptions app)?

[daattali]

I'm creating a store with a subscription that has a product A that gets delivered on Mondays, and another product B that gets delivered on Thursdays. I want to be able to charge a delivery fee for each one of them. If the customer chooses only one of them, then only one delivery fee is charged, but if they choose both then two delivery fees are charged.

I can't seem to find a way to do that. I could do a workaround where I offer a third product C that is a "combination of A + B" that will just have a higher delivery fee. But that seems like more work on my end, and a worse more confusing user experience for the customer.

How can I achieve what I'm trying to do?
