Medication amounts and units

I’ve a similar question relating to units. We’ve a need to describe a quantity of Grays (Gy) in centigrays cGy) and also to a lesser extent volts (V) in kilovolts (kV). We’re using dv_quantity, but there doesnt seem to be an option for these two, or a prefix option on dv_quantity. I think Uuom notes the c (centi) and k (kilo) as prefixes. Obviously there’s a mathematical operation to get to kilovolts from volts etc. Is there a clean way to do this with dv_quantity?
