You guys didn't get it. I'm not talking about modifiers here, I know what they are. Maybe I didn't explain very well... sorry if it's the case. I will rephrase it.
Basically right now, toggle switches on your HOTAS act as button pressers if you bind them the normal way. To avoid that, and have them work as toggles, you need to use the "special for joystick" list of bindings. The problem is, what's available in there is very limited as you can see in that thread for example.
To avoid being limited and bind anything you want, you can always do some lua programming as shown right here. But it's complex and time consuming.
I'm asking that we get something that allows us to do just that but in the user interface so it can be quick and simple.
