Domain Mapping Reseller Suggestion for Other Resellers

Many of us use other resellers for domain mapping other than enom. Rather than try to cater to all of them, why not allow a 3rd option to enter a new tab link and text to send them off to whatever landing page we have for reselling? We can put our instructions on the linked page, and then make sure that the end page of our reseller directs them back to the domain mapping plugin.
