Generally speaking W&B on the 76 is very straight forward.
Plan the lower-decks for final destination only. On main-deck, load final destination from the rear, as well as in A1. Load transit freight from 2L/R (door) and aft. During transit stop, pop the MD door and off-load transit freight. If necessary for trimming purposes, final destination ULDs can be brought forward.
Might not get the most economical trim to transit station, but that's the price to pay if you want minimum ground time.
Don't know if you're fuelling at your transit stop, if so that's likely to be what's limiting your turnaround times. 10 tons, after all, is only 4-6 ULDs and off-loading that will take less than 15 minutes all inclusive if loaded as described above.
