When adding a user to the workspace, I would like to be prompted if an invite has already been sent to this user

When adding a user to the workspace in the "User groups" page, I would like to be prompted if an invite has already been sent to this user, and if so have the option of resending it. 

Currently, Bitbucket only shows the message "Important: Make sure the email address you are providing is working, otherwise the invitation will not go through and any future invitations won't be sent. If the invitations aren't arriving, contact support."
