Hi Shamil,
No you can not Link them to the control surface like that. You can manipulate 1 keyer and then copy that keyer to the other then adjust it.
In live assist there is a copy menu for this. Or you hold the destination Keyer Select button in the Keyer control/delegation (the key to copy TO) and then press the Key Select in the Keyer Control delegation that you want to copy from. The Keyer will then copy all the same values and source.
