Quicker way to enter slips

IS there a faster way to enter timeslips? We now have our clerks entering directly into TS instead of ECenter.

Their main complaint is that they have to keep selecting the attorney when they bring up the client's slip list instead of it already being in there. I saw the slip entry sheet, but you have to do a separate line item for each activity (which would take more time to sort than its worth).  IS there a way to do that? Or at least, a way to set the client up so the attorneys info is already entered when the new slip is created, and we can manually change if necesarry?
