would like ability to use multiple keybinds on the same ability

[hoary lynx]

for instance my weapon is bound to "t" on most characters it would be nice to also have the option to bind it to "1" at the same time so i can choose which to pick and not stretch hand to more comfortable position, i understand i can change the key binds but this is something other games have let me do and is key to how i set up and use my keybinds. (i know there is setting option to add secondary keybind, however this doesn't extend my to abilities bar as i can see)
