Bc2000 (for the BCF2000 & BCR2000)

Greetings all, this is my first post.
Is it possible to build 'radio buttons' ie one button controls other button(s) LED on/off (as well as message state)? I'm using Cubase and also have Bome's MIDI TRANSlator and MIDI-Ox but am wondering if it can be done without programming translations. Cubase has an internal function where one set of controls (Generic Remote) can be "shifted" to control 4 different 'banks'. I'm using BC Manager and have buttons 53-56 successfully switching through banks, but would like these buttons to have feedback like default Encoder Group buttons, where only one is active at a time (turning off previous group LED). Incidentally, the bank function in Cubase has a 'spin edit box' graphic instead of an LED display, so it doesn't have a proper internal LED display(+output?) as it does for Selected Track -which works in a respective radio button manner.

In addition, could someone direct me as to how to toggle an encoder knob's LEDs by way of the corresponding encoder button? This is for toggling on/off sends in Cubase - the encoder knob is presently a variable CC and the button a note, which I want to display as OFF=No LEDs, then back to original state (variable CC when toggled back on).
I hope I didn't make this sound too confusing.

Basically, what I need to know is how LED on/off messages correlate to incoming/outgoing assignments, and how they may be controlled externally. I somehat prefer to forego the toggle setting for most of my uses to avoid extra button presses, but seem to require it to have visual feedback. Any help is greatly appreciated, and excuse me if these questions have already been covered.
