Support adding timestamp to any Markdown tasks

[wenlzhang]

Currently, one may set hotkeys for togging tasks managed by this plugin as "Done" and automatically adding completion date. Similarly, is it possible to use hotkeys for marking any Markdown task (those without the tag #task) as done and automatically adding timestamp? For instance, an example for such a task may be - [x] Task ✅ 202107301526.

Strictly speaking, this is not the main purpose of this plugin, but it would be very useful to have this feature supported.
