Custom Prompt Library - Ability to store and reuse custom prompts as we can for Filters/Views/Groupings

My company has billing period that lies outside of a Calendar month, therefore we are unable to use the standard date prompts (e.g this month) to get the information we need.

I have created custom prompts to get around this but it would save a lot of time if I only had to create them once and have them held in a library, rather than manually recreating on every report relating to revenue.

I'm sure this would be very valuable to other companies that have their own anomalies
