For sure I can.
Suppose that I do want to know how much steem or SBD was sent to steemmonsters.
So, I would like to have a feature in which I can write down 2 accounts, and that in stead of getting all transactions between the 2 accounts back, I would get an overview of how much steem was send from account A to account B, how much steem was sent from account B to account A and a net result.
This way it would be very easy to get an overview.

Hope this example is clear enough. If not, feel free to let me know.

Cheers,
Peter
