Unfortunately the ability to do this doesn't exist as that is designed to show the date the resource was originally posted.
The closest I could find was this add on which is only compatible with XenForo 1.x which allows you to manually update the date a resource was posted. - https://xenforo.com/community/resources/resource-manager-date-change.1572/. You could do a reply and ask if there are plans for it to be updated.
Alternatively, you could do a thread in resource and add on requests mentioning that you would like an add on made that does what you are after and see if anyone is willing to help you out.
