A really powerful and time-saving addition to the Secondary Output section of the render dialog would be options to choose a secondary directory, and
Pre-FX (master) setting for the Secondary output.
This would allow creating a 'clean' pre-master version without any bus processing for third-party mastering, archiving, referencing etc. during the same pass.
A secondary output location could help with organization, automatic backup to multiple drives, or if creating a lossy version for portable listening/sharing it would already be in the proper directory.
Excuse the terrible mock-up skills, obviously there's much less UI space when a 2nd format is active but pre-FX should fit (most important IMO). The secondary name/path options could be accessible in the primary name/path areas, or the render dialog resize slightly when necessary.
