Hello ;] this is my first post here, and im a new blender user (playing around with it for few months).
After years on max its kinda difficult ^^".
Ok so i have a issue with imported bipedal armature that needs to be adjusted for a character but the bone names are already set and it doesnât work with blender X-Axis Mirror 
now they are something like this âcharacter:LeftArmâ for it to work would need to be âcharacter:Arm_Leftâ or âcharacter:Arm_Lâ right XD?
This naming convention need to be preserved since already majority of characters and animations in game use.
Can easily adjust the symmetry without editing the naming of hierarchy?
