Send email at specified time in date column

Hi!

It would be great if the automation: ‘When (date) arrives’ would have the option to use the specified time in that particular column.

We are a training company and we send an automated email to our trainees when the session is ending. This time differs, so I would love to able to not add a time at all and that the automation just uses the time that is in the column.

Kind regards,

Tijs
