Is there a way to create a Contact from an Account, selectively copying over Account fields?

I want to add a Contact to an existing Account, and selectively copy over some of the fields -- at a minimum, the postal address(es) -- and, of course, fill in the Account name in lookup field of the Contact record. This is for one-off things (such as we've established a new contact at a company) so I don't want to do it through imports.

I've seen in a few places references to something that does this kind of thing; I'm not sure if it's a link somewhere or a button or what.

So maybe this exists already, but if so, I haven't been able to find it.

If not, what's the easiest way to create a Contact that inherits some or all of an Account's information?

Thanks!
