Controlling one of multiple servos with a IR Control

My plan is to control a group of servos with a single control, so for that, I need to select with the number keys one of the servos and control just that until I press another number. But to make sure there aren't unexpected mistakes, I want to turn off/disconnect the unused servos until their corresponding number is pressed.

Can I do this by dettaching the unselected servos with detach() or is there another way to do it? Could you tell me how if there's a better way?

If you 'stop' a servo by using .detach() it will not maintain position if something forces the shaft to turn.

If you 'stop' a servo by setting a position and not changing it, the servo will hold that position if an attempt is made to turn the shaft.

I forgot about that, thanks!
