Option to select previous unlocked borders?

Hey everyone just wanted to know what you all thought about the idea of having the option to select borders that you previously unlocked through leveling up? I just hit 150 and the border I just got for my icon is by far one of my favorites ive unlocked to date. Now the problem is I don't wanna lose it after leveling up. Is there an option to filter through previous ones and im missing it? If not I think it would be an awesome feature and one that I don't think would be to hard to implement.
