Giving discounts to specific users

Hi

I have a following request from the business that I'm not sure if it's allowed by the guidelines.

We have a streaming app, in which you can subscribe to certain group of materials. For customers that also subscribe to our other services (in real live, that are not managed or paid in an iOS app), we would like to offer discounts on some of the subscriptions. Preferably this will be done using a different in-app for the same product.

Is that ok?

The closest example I've found is this one:

Cellular carrier apps may include auto-renewing music and video subscriptions in pre-defined bundles with cellular data plans, with prior approval by Apple. Other auto-renewing subscriptions may also be included in pre-defined bundles with cellular data plans, with prior approval by Apple, if the cellular carrier apps support in-app purchase for new users and the carrier provides a mechanism for customers to revert to in-app purchase upon termination of the customer’s bundled service. Such subscriptions cannot include access to or discounts on consumable items.
