Is it possible to both reroll and explode 6s in the same roll?

Hi! Soon, a new version of an RPG is released here in sweden, and in it, you roll d6s. If you roll a 6, you reroll that die (without counting the 6 to the total) and add another die, repeating this until no 6s remain. I have tried experimenting with different combinations of the reroll and explode commands but so far it does not work as it should. Is it possible? if so, how? Any help is appreciated, thanks :)

Exploding and rerolling can be combined but the part of not counting the 6 is not possible with the normal dice roller (that I know of) but you could upgrade to mentor level to access the API and see if anyone could write you a script (if there isn't one already written) for it.
