[FR] Better calendar view for multiple days

### Description

I've some multiple days task, that I need to see on calendar view as a "long task". I mean, clearly see them from the first day to the last day like any normal calendar. If a task run from Monday to Wednesday, seeing it on Monday, Tuesday and Wednesday, as a "long task".

### Impact

Being able to see tasks spread on calendar view. Can be really helpful for managing task over time and seeing if you have done multiple tasks on one day.
