Analysis Workspace provides a built-in "Days Since Last Visit" dimension. However, this is at a granular "day" level. In some visualisations, it would be more useful to see this by buckets, e.g. "same day", "less than 3 days", "less than 30 days", etc.
Since this dimension cannot be classified (using Classification Import or Classification Rule Builder), it would be good if Adobe can create a "Days Since Last Visit Bucketed" dimension to support visualisations that don't need granular per-day values.
