Can items be setup such that lot number is required in one branch and optional in another?

We would like to use lot control in our main manufacturing facility and lot number required to be entered/assigned but we transfer a number of items to satellite branches for sale or use in local manufacturing process. Will lot numbers also be required in the satellite branches for the same items? If lots are optional in the satellite branches, what happens during receipt of the transfer order? Does the lot automatically come over, or do we lose it altogether or what exactly are the options we have?

Thanks,

Mark
