Multi-project review app?

Hello,

Is it possible to get multi project review apps?
I have few projects which build the whole app and I would like to get something like Qovery does:
when I create PR from branch “feature/XXX-2222”, the review app will be deployed with other services deployed as well with either “feature/XXX-2222” if available or develop if the feature branch is not available.

It would make review much easier.

I suppose it could be possibly done using multi-project pipelines, but not sure how?

Anyone has done something like this?
