Date / time picker in automations

When I want to use time trigger in automations I have no possibility to select time. I have to manually enter “10:00:00”. It will be very great to have time picker there also.

This is possible with the use of a template and an input.

But templates are supposedly too advanced for users, so it would be nice to see the process simplified.

After initially replying with a request for a “Schedule” Trigger type here, I realized that is a related, but separate request.
