Add host username to screen capture filename

As many companies do, we have multiple techs work on guests for the same ticket. We take screenshots of progress, changes and results for obvious quality assurance and CYA reasons and attach them to our third party ticket system (CommitCRM). In a scenario where multiple technicians would work on a guest machine, its a painstaking process of renaming each filename with the host's username in it so there is no conflict when attaching to the ticket. Can we add a way to modify the name utilized when saving the screen capture?
