How do you add custom Package types and Lead forms for use in the Component Classification dialog?

The default lists provided for Component Classification by Package type and Lead form type is limiting and does not cover all possibilities. I would like to add some additional options so I can provide a more thorough check to make sure my footprints meets the IPC-7351 spec. For example, the component spacing and toe/heel/side fillets for an 0402 discrete are much different than a 1206 discrete. I would like to create a component type CHIP-SMALL with a lead form C-BEND-WRAP-SMALL. I understand I will have to create additional ERF rules to support these but I cannot find any info on how to add your own; only component type documentation shows up, not package type or lead form type. If I manually add the new type uinder the CLASS-1 cell of the ERF manager it does not recognize it and will not show it as an available option for other rule sets.
