Cert Numbers for cards

I have cards in my collection that I have graded. I can edit the card but I can not add in the cert numbers for my cards. it looks like you guys do not support this for any of the graders. it doesnt look like you can do this in either mobile or your desktop version. It also appears that even if you scan cards in as graded they still don’t populate the cert numbers. what is the point of having a cert id column if you dont populate it? you guys should add this so people looking at their collections can go to their graders websites to look up the card or to look up their pop reports. it would be so convenient if you guys just linked people to the graders with the cert number off the bat.
