Multiple screens sharing VDINs over master bus

I like the current features of the master bus for shared information. 

I have written several programs that require multiple screens to work as if they were the same user stations. It would be great to have the VDINS added to the master bus so that the data can be shared. Currently I am having to dedicate a J1939 bus as well as write CAN frames each way for output and feedback to control VDINs.
