Multiple PLC's in one PLCnext engineering project

Hi
Can we expect any time soon in PLCnext engineering the possibility to create one project for multiple PLC projects?
I am starting a project with 32 PLC’s, standard panels with one AXC 1152 PLC which I need to modify accordingly to the configuration of the machine. Now I need to create 32 projects separately.
Other question, what is the best why to connect several AXC 1152 PLC’s for data exchange, Profinet or Modbus?
Thanks
