Definitely need this feature! There are other similar ideas in the forum about this, but upvoting here because it looks like this one has the most traction and this should be something HubSpot prioritizes! For my use case, this is really important for complex open vs closed ticket volume reports - see more below:
As you can see in my screenshot, I am breaking down the graph by the ticket status, but it doesn’t give me further customization of how that data is broken down, it just breaks it down by each ticket status that is known. Hovering over the breakdown, ideally all of the options before “Closed: Conflicts & Disputes” would be grouped as 1 big number called “Open” and the “Closed” would be a group of the “Closed Conflicts & Disputes” and “Closed” so that there are only 2 different colors on my graph. Perhaps clicking on each color could give me more details about which status they are in. I just don’t need the graph to be THAT granular by default. I think there might be a default open vs closed tickets report, but I believe it only works for one pipeline, not a combo of pipelines, so giving us more flexiblity to group data our own way would be great!
