Wrap a .ini file with .intuneMac

Hello, I am new to Intune and am trying to learn how everything works.  My client is migrating from Windows to MacOS and we are using Intune as the MDM.  My question is this:  I would like to setup our RMM agent to automatically deploy on new Macbooks that they purchase, but the agent setup requires a .ini file to direct the installation to the correct site in our MSP.  I have found instructions on wrapping the .pkg installer as a .intuneMac file to upload to Intune for deployment, but I have been unable to find anything on wrapping the required .ini file with it.  Is this possible?  If so, how do I do it?  It seems like this would be a pretty basic requirement to installing a lot of LOB software...
