Matrix: Using the HCI (host computer interface) can I over write a key configured by ECS

We are using VSM to control our Eclipse Matrix via HCI , can we get the VSM automation system (as provided by LSB/ Lawo) to re-program keys on the panels that have been central configured by ECS or HX
The answer is yes VSM via the HCI protocol can overwrite ECS/ HX configured labels on panels keys
