Day divided on 2 or 3 parts

Hello,

At this time inside ProjeQtOr the days are in 1 part, and then equal to 24 hours.

Is it possible to have an option that cuts the days into 2 parts => 2 x 12 hours ?
And into 3 parts => 3 x 8 hours ?

It will be tricky as this change could impact deeper the time and expense calculation system.

These configurations could be inside the standard calendar view ?

In my sample join, you can see days cut in 3 parts, with a part = 8h, and then 3 parts for a day = 24h

To explain more my idea, I could say that inside the parameter window, I will be able to choise for a day if I want 2 or 3 parts, and for every part, the time duration.

For sample, a day cut in 2 parts = 2 x 12h in max
For a day cut in 3 parts = 3 x 8h max

And at the end, the planning must be able to start the tasks inside the right part of the day !
This will offering the possibility to manage workers with a calendar in 2 or 3 teams per day !
