E1 Thermostats - Different Smart Schedule in each room

I have three E1 thermostats, all in separate rooms. I want a different time and temperature for each room.
If I go into the Smart Schedule on one of the thermostats, I see 3 Agendas where days, times and temps can be set.

The problem is that once a day has been used on one agenda, I can’t use it on another.

e.g. Agenda 1 - Mo Tu We Th Fr Sa Su - times and temps set

If I try and modify Agenda 2 to use in another room , when I add days to that Agenda they are removed from Agenda 1.

I’m I using the wrong approach? Is there a better way?

Hello, unfortunately, E1 has this algorithm of operation. If you want, you can use my smart schedule 2.0 method Automation 2.0, lesson 10, room climate control. Creating a smart heating schedule for radiator thermostats (E1, W500, W600)
