Grouping dates by calendar - also descriptive months ?

Hi it would be great to be able to group series by trimester.



For example if we want to compare signed opportunities by quarter, either we have to create 4 tables at the moment with filters on specific dates (need to rework the dashboard each year), or make due with visualization of 3 months. But we would like to group per quarter for the whole year and compare par current versus last year.



Also, in the visualization, could we have months in text and not numbers ?



(January, February, etc... instead of 1, 2, ...)
