Set User Account Expiration Date

Dear Atlassian Team,
we would appreciate if you would implement a new feature called "User Account Expiration Date".
In Jira User administration there should be a possibility to set an expiration date for an account.
We Use Jira internal and for our customers. So we have many Customer Accounts running, but we don't have
an overview if the user of the customer account is still an employee of our customer. For some Projects we have
special security orders from our customers. And we don't want that someone can get information from our jira, if he
isn't still an employee. So it would be a very helpful feature. For completion an automatically deactivated user should have
a "button" to ask jira administrator or project administrator for reactivation.

Thanks a lot for implementing in the future
