Macro to temp control token?

Is there a way to give a player control over a token when they roll their macro and other way?
For example if a player has an attack that shifts the target, is there a quick way to let him gain control of that token?

No worries if it not able to be done with just macros thats okay ^_^ Just wondering if it was. Thanks for the reply.

The simplest way to do this is just to assign that player control of the token foe the allotted amount of time.

The macros are very limited in what they can do. They can do rolls, do some math, and interact with the chat. Their only interaction with objects are the attribute calls, and these are read only. They can not do any set commands, conditionals or other forms of the Javascript logic.
