Auto Index switch for MFN role

3DX includes a feature that allows authoring mode to automatically switch to index mode after a user-defined time (see Fig. 1). However, this feature is currently not available for the MFN role (see Fig. 2).

Questions:
1. Is there a reason why MFN does not have this functionality?
2. Is there a workaround rather than switching manually?
3. Is this functionality for MFN in the pipeline?
