Hi Zsofia,
sorry for the late response, but it was my last week before vacation and I had a lot to do.
Here is my proposal. Maybe not the most beautiful, but it seems to work (at least as I understood your problem

Please let me know whether this meets your requirements.
It would be great if someone has proposals to simplify the project. Please keep me informed.
Have a nice weekend.
Regards,
Jochen
