Programs should be able to be scheduled/sent multiple times a day instead of once

Currently, a Program JO can only be scheduled to sent once a day. We would like for things like emails to go out multiple times a day as the information that is used to Filter our Participants is updated constantly, meaning there is often a 24 hour delay before they are picked up and sent the email.

Primary use case in my situation is a Welcome/Kickoff Email for new customers.
