NX Simulation files managed through Work Group Manager

Currently WGM only allows for a single simulation file (must be same named file as CAD object) to be automatically checked in as attached content.  In real life usage many times there are more than 1 .sim file associated to object and as the .sim file is required to have same name as object in order to be uploaded there is a single .sim limitation otherwise user must manually check-in other .sim files as attached content.  Automatic upload should be able to handle more than one .sim file per object.  How can this functionality be achieved?
