XF 2.2 Promotion Downgrade

[htsumer]

I'm getting promoted to Group B. Later, this group B buys group C as a paid group.
It lives the special code permissions of group B.

Since this goes to group C, the membership of group B is stuck.



My question is how can I drop it from Group B. If it's a C that he bought, it's like leaving group B.

 

[htsumer]

I have to manually remove group B (ADAY ÜYE) (ID:27)

 

[htsumer]

If group C bought it, remove group B. I need a logic like

Edit the promotion for group B to only apply if not in group C.

 

[htsumer]

There must be some logic.
/admin.php?user-upgrades/

Regardless of which group to buy here, the secondary groups should be deducted.

While in Group A, it buys Group B, but still has some restrictions as Group A is active.

Note:
group A in the picture will be B
Group B will be C. I typed wrong

Should I do it with promotion management?
There is no reason to leave the old group in the promotion management.

Where will I do it? There is no such criterion in the promotion (/admin.php?user-group-promotions/) section


It would be great if there was an option in Purchased Subscriptions to have other groups free upon purchase.

Let me explain again.
Promoted from Group B to Group C.
Group C bought Group D.
Member has 2 groups C+D
Now when he buys group D, he must leave group C.
