Track Contact's Employment/Account History

Thank you in advance for all of your help!

Is there a way, within Zoho, to keep track of a contact's employment history? For example, if John Doe is my contact at Account 1, but leaves the company and is hired by Account 2, can I...

...maintain John Doe as a former employee under Account 1, while simultaneously listing him as a current employee of Account 2?
...view John Doe's employment history on his contact page in addition to the account he is currently associated with?

I'm sure there is a way to do it, as I've used this feature in other CRMs before, but I can't seem to find it under the customization menu.

[eta: I changed my example contact's pretend name halfway through... sorry for the confusion!]
