To use this macro:
Select a note in Agenda. Invoke the macro (it’s set now to use the status menu, but invoke as you wish).
Then, either type in a single date in the “date” field. Or, if you want to add a range, type in a start date (using natural language if you want) and an end date. Note should now update.
This allows you to type dates if you prefer that sort of entry here (as I do for adding date ranges).
