Similar to weapon groups it would have an extra column with numbers, one column - so using Right Ctrl on it will just iterate the selected group from 0 (disabled) to 7 in a repetitive manner. Again, similar to weapons, it would add 7 rebindable hot keys to iterate through modes of an according group. Furthermore, it would require an information column to display current mode information.
This way you could easily introduce something beyond ECM modes, for example:
- toggle AMS on/off
- switch munition type (LBX and regular ACs)
- switch Ultra fire activation mode for UACs
- introduce activatable/multi-mode modules
