Great idea! And probably not too difficult for us to add. Let me make that feature request.
Linear Asks put together an ask for having an end date on credentials.
It should:
1.
Support Day, Month, Year.
2.
Fill out LinkedIn with a true end date (only send through month, year)
3.
When that month is over, the certificate should be marked "lapsed" or "expired" - need to explore common language in this space
