Is there any software for automatically scheduling tasks by time, broken down by day of the week?

Question

Time Management

I have a main schedule, which is busy with the main things. Also, tasks appear periodically that must be completed before a certain time. Are there programs that will help you do the following:
1) fill the main calendar with tasks
2) when adding a new task that needs to be completed before a certain date, they will find free places in the schedule and break this new task into several days, automatically filling the calendar?

Answer 1

The first thing that comes to mind is OmniPlan. Although, of course, it is only convenient for building a sequence of tasks within one specific project.

Answer 2

Someone knocked on VKontakte on this topic, but deleted all the messages, please knock on the door.
