Changing BACnet Instance Numbers on M172

[Aribbs]

I'm looking to program an M172 to be a direct replacement for another PLC which has certain BACnet object instances. When I try to change this in machine expert, the option is greyed out and I cannot change this.

Is there any way to change the BACnet object instance number?

It's not possible, the instance can be changed only on the Device object, the instance of the other objects AV, BV,... objects is automatically assigned starting from the lowest one
