Support for two control rigs at the same time

I would like to know why isn’t possible to control two control rigs at the same time. I would like to make a reload animation for the weapon but if I select the character I can’t select the controls of the weapon anymore like in the video.

I know this is not supported in 5.0 but is there a chance to add this feature in the future?

have no idea if this works but maybe you can press CTRL and then click on each rig.

Thank you for the suggestion but I have already tried it.
