[otrs] Can I create stats for time units?

Hello everyone, I've had a bit of exposure to OTRS, as my company has been using it as our ticketing system for months now. We recently made the decision to start recording work units, and I wanted to know if anyone knew of a way to incorporate work units into the STATS objects. More specifically, I wanted to get the work units (by minutes or hours) for a particular ticket queue within a given time period. Any suggestions? ~Myles
