What is a completely new functionality you want to see added to Power BI, that would unlock new possibilities? things like- Field Parameters, Calculation Groups, Fx attributes, DAX query view.
I don’t mean new visuals but a brand new way of doing things like the before mentioned features.
Lets say:
Ability to use Calculation Groups/Items anywhere you place a Measure. This would greatly decrease the number of measures that you need to create in your model. LY, YTD, YOY and other measure variants would be accessible for display using this dialog options. This would work in Cards, Reference labels, Data labels, Tooltips, as a single new column to Table/Matrix – just anywhere you put a measure.
What do you think? I actually believe this could be quite feasible, since the implicit column aggregate measures are basically calculation items.
