CRM Files Directory

Is there any way to choose where the CRM files are created? Currently they are created on the root of the C drive and that really is not a good place for them. I would prefer to keep all files related to the emulator within the same folder structure to keep it portable. I noticed there is a setting for the BRM files directory, but no option for the CRM files. I tried adding a CRMFiles setting to the fusion.ini file, but it does nothing and is removed once the emulator loads.
