Is there easy way to move logged calls/ tasks from an account record to a potential record

Is there easy way to move logged calls/ tasks from an account record to a potential record

We'd like to change the way we log our data so that all activity under a potential is stored there, rather than the individual contact records associated with that potential which is what we have been doing so far. Is there a simple and quick way to do this without having to create new call and task logs under the potential tab,

Thanks
