SAP Design Studio 1.6, dynamic forms

I am new to Design Studio and SAP-World. In my project I am designing a User-Interface to generate Reports at the end. I have a Tab-Panel, within this I need to preselect the number of queries to the database and depending on that dynamic numbers of forms should show up.

For example: User A chooses a country (tabstrip) and needs different reports from different cities so he chooses in a dropdown-menue 4 as number of reports and a equal number of forms(all have the same design) pop-up. After all form fields filled up, User A presses Start and gets his reports.

Do you have any ideas how to solve? Thanks for your knowledge and creativity in advance!
