Interval section for manual planning/planned intervention

Both the "manual planning" and the "planned intervention" tables are at "half-day" level, that is, you can assign to the resource 4 hours at a time.
I discover that pressing Ctrl, you select the full day, so you can assign to the resource 8 hours at a time.
Is it possible (with a combination of keys) to select an interval? For example, I click on Monday morning, then I click on Friday afternoon and the entire week is automatically selected?
