Rifle Scopes adding zero stop turret to S&B?

[ccoker]

I have a S&B 1.5-6x42 Zenith with the flashdot #9 reticle
I LOVE the scope but would love it even more if I could have a zero stop elevation turret added to it.
It is FFP and has .1 MIL adjustments

Anyone know if this is possible?
I plan to call them on monday to find out but thought someone here might know

thanks
