N Expense Transactions window can I see the list in "CATEGORY" order where each category is grouped eg "FUEL & OILS"?
With the current expense's transaction list it only filters in a-z format on the transaction page and at this time can't be filtered by category groups. This also to extends to filters that may include or exclude specific categories. I would encourage however to lodge this type of feedback which can be found;
Select the Gear Icon in the top right
Then you can select the Feedback option (below the Profilecolumn).
