Multiple selection when entering services/subcontractors/components/construction areas

It should be possible to make multiple selections for some topics when creating the construction diary.

First and foremost, it should be possible to enter the services directly for several days. These sometimes do not differ within a week. Currently, you have to enter each day manually. This can definitely be simplified.

Regarding entering subcontractors:
We work on large projects, so our subcontractors have a large number of fitters on site and are therefore also active in several components/construction areas.

In addition, the activity should also be possible as a multiple selection.
