It's currently not possible to add quote status to a report in HubSpot at this time. I could see how having more drill-down options would be helpful though 🙂
One possible workaround to consider is to make a custom deal property and call it "quote status". You can update that property when a quote is created or updated, and from there you could make deals report that uses the custom property.
I would recommend upvoting this related idea in our Ideas Forum and commenting on why this functionality would be useful. Our Product Team who monitors the forum regularly will be able to read your feedback and take it into consideration for future product development.
