Hi,
With PE you can add new memeory segment but in your case I think the better way will be to handle it manually.
In Processor Expert you can define if you want to build or not the cmd file.
We recommend you to disable this option.
By this way the cmd file will not be updated during the PE rebuild.
Option is in bean Inspector under Build Options.
In Generate Linker file, select no.
