Changes in selection Heirlooms

I have a proposal to change how players interact with heirlooms. I own a Cobalt Katar and believe this change could be implemented for all universal heirlooms.
First of all - multi-select, like weapon or legend skins. All owners want this feature. Like you mark your favorite skins and they will change every match. if you have recolors of katar or katanas or something else universal, it will change in next match. i guess every content creators will thank you for this, because they change heirlooms manually rather than automatically to record content.
Secondly, equal opportunities in animation. Some heirlooms have special animations, when the character crouches. For example: when you crouch with dual katanas, you will see animation with sushi, or if you crouch with power sword, you will see a trophy of ALGS. In my opinion, all universal heirloom (and cobalt katar) must have 4 inspect animations and special one in the crouch position. This will allow players to intelligently compare heirlooms and choose them to their liking more consciously.
And finally, this is my personal request. If you have cobalt katar, like me, you can create only 3 type of them. But in theory, player can create 100+ variations of their own katars. Can you increase the amount of customization to at least for five or six?
