Is there a way to carry over a tag put on a contact to a deal that is associated with that contact?

Is there a way to carry over a tag put on a contact to a deal that is associated with that contact?

We recently started applying tags to contacts and are trying to apply the same tag that is on the contact to the deal the contact is attached to.

For example we have a tag called 'MM Telesales' on certain contacts and is there a quick or easy way to carry over that tag to deals we have attached to those contacts?
