Slack notifications - formatting options and delay

[David_Pethick]

I notice the way that Slack notifications are formatted changes, based on the order in which data is entered into Airtable. I’d like my slack notifications to have a consistent format.

Can you please implement two changes to the Slack notifications options:

1. Add an optional delay (say 15 minutes) - to ensure all data has been entered before the notification is fired
2. Allow the fields in the notification to be selected and ordered by the user
