It would be nice to have a setting per channel that, when activated, adds events to your calendar for tasks that you worked on.

I have to track time in my companies time tracking tool. I do that once a day as part of my shutdown process. The tool gives me a calendar view with an overlay of my outlook events. This overlay is a great reminder of what I actually did and what I need to track there. If I timebox a sunsama task this works like a breeze. But for tasks that I did not timetrack I just see empty spaces.
