Hi,
PowerApps community.
I have created an app for visit reservation in the office for COVID times.
It is simple pick a date and department SP form.

I am trying to achieve a possibility to book couple of days in one submission.
I am aware that this is not possible using form, I can use regular controls to create collection and patch it to SP but I am not sure if this is even possible.
Could someone tell me how to start? I have not found any solution by myself..
