T4 cat trade in

Jwt2020

What I feared the most just happened. I had 6 t4 tech in my overflow and 3 t4 mystic also in my overflow. I'm looking for mutant cats so I gamble and trade in 3 of my t4 tech and get 1 mystic. So i wait a day or two because i'm pissed but finally trade in my t4 mystic and get another tech cat. For the love of god, if he have to trade in 3 friggin t4 cats, give us the ability to choose what cat we want. You already have this ability in your code, make it happen please.
