Add "Minutes" Option to Smart Campaign Qualification Rules

[Anonymous]

Currently smart campaign qualification rules allow you to select an option for "once every [x] hours/days/weeks/months"

I am finding this is not flexible enough for certain use cases, and it would be great to have the ability to increment in minutes. 

Example: there are behaviours we want to track that are quite fast paced -- like web sessions that last 30 minutes or less and that may start again. 

The current minimum increment of one hour is not flexible enough for these scenarios.
