Way to tell if I already have a creature in my stable while summoning

So I want to have one of each monster in my stable eventually. After I breed some of my monsters, I have a hard time keeping track of what monsters I have in my stable. Usually I would use the asterisks from the list of cores I have when I am summoning monsters, but it only tells me if I have used the core before, not if I have the monster in my stable.

Is it possible to add a different way to indicate that if I have a particular monster or not in my stable while I am summoning?

When you are summoning over on the right side of the screen under the creature family it has a message like “2 @ Stable” if you have any currently in your stable.
