Emotes

I recently got into emotes, and find it to be really fun and a great way to communicate quickly for less important stuff like a gj to a teammate or a laughing emote after you turn around a 2 man dive after your lane opponent has been spamming his mastery. Buuuuut I wish you could change them in game even if its changing presets. If this option was available I would probably invest more in the emotes. Thoughts? Am I alone in thinking this would be super cool?
