Add optional task templates for lists

[PostPollux]

Is your feature request related to a problem? Please describe. My problem is that it can feel quite clunky to add new tasks. Especially if it is just onetime todos and I want to have rewards for those as well. Without a template it lots of clicks. Fortunately we have templates now, but it still is clicking on new task, then on the template list, then on the template. So it is two extra clicks that we could avoid.

Describe the solution you'd like It would be great if you can set a task template for lists. Currently if you are editing lists, you can only set the Tag color and the name. Please add the possibility to optionally add a task template. So when I only show that list and then click on the big "+" in the bottom right corner, it automatically uses this task template and I don't have to always do these two extra clicks. I would only have to make the taskdescription and I'm done.

Also, if "All" is selected as list, there could be a small "+" button after the list names, so it automatically preselects that list when clicking on that +. And if that list has a default template it will use that.

The design of the plus button should of course be different, this is just to illustrate where I would expect it.
