It depends on how carbed the beer is in the keg already.
If you're at a known volumes of CO2, you could subtract that from your final desired volumes & prime for the remainder. It likely won't be exact, but it'll give you a relatively close starting point.
On a side note, I've used those Coopers carb tabs before. They're kind of a pain in the ass & rather inconsistent. Some of them are next to impossible to fit through the mouth of the bottle. There's another brand that makes smaller ones that are a little better.
Honestly I don't get enough difference between forced carb & natural carb to make the extra effort worth it. If it were me I'd just CP fill off the keg & be done with it. Or if I *really* wanted natural carbed bottles, I'd set aside enough to do a 6 pack before I kegged it in the first place. Then you just calculate for the smaller volume... about a gallon.
