[O] Repeat three times a week

[Cecil Westerhof]

I have an event that I like to repeat three times a week: on Monday,
Wednesday en Friday. Do I need three entries like:
* TODO Do It
  SCHEDULED: <2018-04-06 Fri ++1w>
* TODO Do It
  SCHEDULED: <2018-04-09 Mon ++1w>
* TODO Do It
  SCHEDULED: <2018-04-11 Wed ++1w>

Or is there a better way?
