Use allthread as smart fastener?

I would like to be able to use allthread instead of a regularboltas a smart fastener. I use the piping features extensivelyandwould like to use the smart fasteners to propagate thestuds/nutsto the flanges, but the only choice I can find in thetoolbox is aHeavy Hex Bolt w/ nuts. Does anyone know how to dothis? Or whatdifficulties I can anticipate in trying to accomplishthis?

Thanks,
