Often we will create presentation variables in dashboards, and then add formulas to insights in the dashboard which refer to the presentation variables. This creates a major limitation because the unlike other formula columns, these columns cannot be added to a business schema (since the presentation variable does not exist outside of the report). This impedes usability because usually only our data team will be able to add columns that require this type of formula.
It would be great if we could create presentation variables which exist independently of reports, and then add those to reports when we need to use them. Then business schema's could include this kind of formula.
