How to configure subscription with multiple offers

Hi all,

I’m launching a subscription service that consist of a premium subscription with the possibility to purchase it monthly, 3-monthly and annual.

I’d like to offer also two intro promotion:

1. single purchase of a month subscription for a very discounted price, if you have a promo code
2. single purchase of a month, 3 month or year subscription for a discounted price + a free trial of 1 week, otherwise

I’d also like to offer the second option to the people who bought the first one after their month finished.

These offer are not renewing, so at the end the base price will show up.

The problem is that I cannot figure out how to configure these subscription on both google and app store.

Any help is appreciated.
