Unfortunately, I don't know of a way to do it but hopefully someone more clever will chime in.
For the future, pick up a little $2 presta adapter, which is basically a nut that couples to the presta valve on the one end and depresses the schrader pump on the other:
You can get 'em at Nashbar (
http://www.nashbar.com/profile.cfm?c...All%20Products) or probably any LBS. I keep one in my wedge pack at all times!
and an easy way to store them ON the bike is to put a long allen bolt thru one of the rack mount holes on the chainstay, and thread the adapter onto it. (i find that peopel steal the adapters otherwise if you leave them on the wheels....)
