Is your feature request related to a problem? Please describe.
I'm using Todoist as an Obsidian inbox for quick input. I'm currently using a quick-add script to do it, but it is quite unpleasant and slow.

Describe the solution you'd like
I'd like the same type of input as I found in the obsidian-google-tasks plugin which basically have an obsidian command insert tasks.

It triggers a selection menu like that :

Describe alternatives you've considered
The alternatives are the quick add script I'm using but it is terribly inconvenient and not meant to be used by normal users.

Additional context
There's a screenshot above.

%% Waypoint %% Which will actually get replaced by the contents and kept up to date with list. This would enable you to search on tasks using the global obsidian search as well.
