Can i connect this with car listing subscription? So that when i pay one subscription for example (silver subscription) with max 10 listings and that with only this subscription i have to pay 3$ for additional listings when i go over 10. Then there is a gold subscription with 20 possible listings and when i wanna add more listings then i only have to pay 1$. Is something like this possible?
