We use EasyWeek for renting our studio rooms and some equipment.
We created the rooms and equipment as units.

At the moment we have 7 units and when we need to block time for internal usage, we need to do it for all 7 units to hide that time from clients in the widget. It is annoying.

It would be cool to have select option in the dropdown like "Block for all".

We use this function very often and so for our business it is important.
