Yeah, go ahead and sanitize your bottling bucket and all the equipment you use to bottle with. Put the priming sugar in the bottling bucket and then open up and pour each beer into the bucket and bottle as normal. Or you can get the amount of sugar you use, divide by how many bottles you have, open each bottle up, add that amount to each bottle, recap, then shake and store.
