Multiple days planned in task- assignment manager does not propose any time

Hi,

We are using Field Service 11.5.10.2. We have made the basic setups to use the assignment manager and assign tasks manually from assignment manager.

My resources are assigned to calendar and their shift is 9 hours daily. If I plan a task shorter than 9 hours and open assignment manager I can see the available time slots in green. But if I plan a task longer than 9 hours, it does not give any available time slot, all resources appear with the yellow sections showing their shifts. I would expect it to propose the first available day and continue with the next day. Isn't it possible to mark multiple days in green for assigning the resources?
