Exploding Dice question: Other numbers?

in nWoD there are some powers or items that allow the Exploding target number to be other numbers in addition to 10 on a d10. for example, normally tens explode, but some powers allow 9s to explode as well. is there a way to do this? thanks!

Exploding dice instruction are here : <a href="http://help.roll20.net/dice-rolling-reference/" rel="nofollow">http://help.roll20.net/dice-rolling-reference/</a> They use an example of how to make 10d6 explode and I just played with it to make 1d9 explode and 1d2 explode. To make the dice explode you put a ! at the end of the dice. example 1d2! will explode on 2 and 1d7! will explode on 7's.

I think what Nico meant was to make a d10 explode on 9's & 10's, or possibly a d10 explode only on 9's. That is a different beast to d9. :)

thanks Metroknight, but yeah, i was thinking more along the lines of what Tymanthius said. using a d10 and having both 9s and 10s explode.
