That is correct.
The changes I made to the OIR rules pertain to which folder I store promotion request and change management files in. These are stored by year, so I have to make the change to my OIRs yearly.
Store your modified OIR files in a dedicated directory for 3 reasons: 1) you know which OIRs have been modified, 2) you don't have to download it again and 3) you can make future changes and just Edit-Browse to install.
