[Suggestion] Removing all the transactions involving a sub list of the members of a project.

Hello,

I use one of my project in MoneyBuster to register my everyday money exchanges with my acquaintances. A feature that I miss is beeing able to remove the transactions between me and a particular person.

A way to achieve it would it be to be able to search transactions involving a sub list of the members of a project, so that we could select all the transactions and remove them.
