Dice explode on "1" rather than default "6"

Hi, I'm running a Chris Perrin's Mecha game where the goal is to roll less than the target value on a Xd6 and the dice explode (allowing additional rolls) on "1"s, rather than the default Roll 20 "6" (or other highest dice value). Is it is possible to simply (he said knowing nothing is simple) change the dice roll to explode on rolled 1s rather than 6s? Has anyone run this game or similar games with this mechanic, and successfully programmed the dice roller to do their convenient bidding? Thanks. 

It is possible to do this, but how do you use the dice. Is it a simple sum? In which case you can just do: /roll 10d6!1 If you're rolling against a target number, say 2, you can do this /roll 10d6!1<2

I will give that shot! Thank you. UPDATE: That worked perfectly. Thanks again, that was exactly what I needed to know.
