Legend Specific Binds options - Feature Request

Something that has occurred to me after quite awhile of playing is that I can't do legend specific bindings and that it would be a nice feature to have where specific binds are loaded based on the legend you picked. Team Fortress 2 actually has a similar feature but you have to use class config files for it. ex. Scout.cfg , Sniper.cfg, Demoman.cfg, etc. Now this is largely irrelevant in Apex Legends due to how similar most the legends are, but I do think there's a couple exceptions. 

Case 1. Gibraltar Shield

So for activating a Tactical I use mouse5 which for most legends works great, but for Gibraltar I'd MUCH rather have mouse5 be his shield rather than the dome. As Gibraltar would benefit from his shield A LOT more frequently than his tactical.

Case 2. Lifelines Ult

Lifelines ultimate while super useful, isn't exactly a bind that I necessarily need to use in a split second notice/decision, and thus doesn't  necessarily need to share the same bind as all the other legends.

While I could circumvent this by making specific keybinds exec individual bind cfgs based on the legend I select but I'd really like to see this feature be available for everyone and regardless of platform.
