Automatons - Schedule 'between the hours of'

Automatons - Schedule 'between the hours of'

I don't know if i'm missing the obvious but is it possible to schedule automation's say between the hours of say 09:00 to 21:00? 

for example:-

Automation 1 needs to execute:-
  • Monday to Friday
  • Every 30 minutes
  • Between 09:00 and 21:00

I can see the option to select the days for the automation to run but It appears the only time option is single specified time
.
