Are Custom attributes of a DNG Module available through LQE to be used by RELM & JRS?

I am using version 6.0.3 and added some custom attributes to a DNG module to help track modules by "subsystem".  the subsystem is an enumerated custom attribute.  
When I build a JRS report, or a RELM view, I don't see this attribute in the "add condition" dialogue for these respective tools.  I am trying to understand if custom attributes for DNG modules are part of the LQE index, or JRS and RELM have not implemented the ability to read custom attributes on modules.

Please help.
