Computed Attribues created from System generated datasets

[#1]

Description - It would be nice to have at profile-level the amount of emails each profile have received and opened in the last 30 days.

Why is this feature important to you - It would be possible to address journeys based on communication-engagement withouth having to do it at audience-level.

How would you like the feature to work - a computted attribute that returns the count of emails a profile have received/ opened in the last 30 days, something link:

xEvent[_experience.customerJourneyManagement.messageInteraction.interactionType in ["open"]].count()

Current Behaviour - Computed Attributes currently do not support System generated datasets
