Control the dispatch of documents

In the record set-up, as a customer I would warmly welcome if it were possible to set up per record at which time the documents are sent. For example:
Invoices in the evening (=6-7 pm)
Orders (=Minutely)
Reminders in the evening (=6-7 pm)
Tour documents (=Minutely)

New field "Dispatch time"
In which the following values can be selected:
Morning
Midday
Evening
Minutely

Accordingly, 4 job queue entries would be created for EDS.
The customer himself decides at which times his documents are sent.
In the task queues themselves, the start time/end time would have to be defined by the administrator.
