How to modify User Id for Module Provisioning

We have a number of CB Content Modules that will be unpublished or published due to user's bookings/subscriptions ("module provisioning").
Therefore user_id has to be dynamic. Module may booking by different users when one has unsubscribed or periode has ended.
How can we keep the user_id as a variable in this specific case with:

- Auto Action (when user has booked -> set module to "publish" and set user_id to id of user who has booked a specific service or subscription);
- CBSubs (we havent subscribed to it yet - so don't how it would be able to assist here);

See screenshot attached of sample CB Content module with static user id.
Pls. let me have a direction how to resolve this.

Thank you in advance.

You're needing to modify the contents of your module based off an auto action? I'm not sure what the best approach is for that. I guess you could use a Query action and modify the module database row in _modules table. CBSubs won't handle this at all. That's for accepting payments as a website. It isn't for accepting payments for individual users (you can't pay another user).

There's probably a Joomla extension already available for selling ad space, which is what it sounds like you're trying to do. Even using Joomlas built in banners component may work better.
