Package purchases

It would be nice to track package purchases through retainers. That way the time purchased can then be tracked on the time tracker and invoiced and paid with the retainer. I'm curious how other designers are keeping track of the time spent through package purchases. We do not charge per room. We charge an hourly rate and have worked around how DF is set up for charging per room instead. This is the only hole we can find, because once a client purchases through our packages page its like we have no way to keep track of the hours they've purchased.
