Adding FK constraints on multiple column in PHPMyadmin

Question

A Picture is worth thousand word. In the above picture we can add FK constraint 1-1, like I can reference UserId to another tables column but If the situation is like this ,

ALTER TABLE `userfrnd_source`
  ADD CONSTRAINT `userfrnd_source_ibfk_2` FOREIGN KEY (`userId`,`friendId`) 
  REFERENCES `user` (`userId`,`friendId`) 
  ON DELETE CASCADE ON UPDATE CASCADE

How can I do this through PHPMyadmin, I know Using SQL we can do but with this tab is it possible?

In Relation view, having more than one index column in the foreign key.
