I am trying to change the sort order of the buffers after doing helm-multi-swoop-projectile:  I would like the ordering to take into account the years in the directory name in which the actual file is located. Is that possible at all? The desired ordering would be: Regesten.txt|P5 (1609-1610) Regesten.txt|P23 (1637-1640) Regesten.txt|P44 (1700-1701)
