Category break-down for group spending

I use the Travel Spend premium version (honestly it’s awesome) but i was surprised to see that for a group trip, I cannot access my total spending broken down by category. It is only available at the group level.

This seems counterintuitive since

  1. Category breakdown is available for a solo trip and premium is supposed to give access to enhanced analytics
  2. You can easily calculate total spending by category at the group level from the individual spending but not the other way around

Am I correct or am I misusing the app ?

Thank you
