Manual waypoint creation by external request?

[is-this-a-comma-or-period]

I would like to create waypoints by a) events like Tasker detecting screen unlock or screen on, Wifi network connects etc b) using Quick Toggles from notification area (maybe also with Tasker)

I do not expect any interaction on waypoint creation. No comment text or photo creation. No confirmation. Maybe a return value that Tasker would know whether creation was successful.

Could you see yourself implementing an external call for waypoint creation?
