Binding Multi-State Button

How do I bind different tags to a Multi State Button in Perspective view?.

I have 3 modes. Auto, Manual, Disable. I have a specific tag value indicator each state is on. A specific tag value to write the command.
How do i assign a bidirectional tag to each button?

For the state, I would use and expression structure binding with a transform to manipulate the value to display the correct indicator, though you may find it easier in this instance just to have three separate buttons instead of a multistate - that way you don’t need to do anything particularly special to send the right value to the right tag.

@jonathan.taylor hmm could you show me an example?
also where would i set the expression to
Control value? I am a little confused as to where to set the expression under.
