I'm creating a custom settings file for different sites who have different needs.  When it comes file export options (File>save as>STL>Options for example), I don't see any menu where you can set these.  But, it looks like when you create a custom settings file and select the "system options" to export, it remembers whatever file export options you last set.  If this is true, do you have to open a model and do a file>save as in order to set those options or is there another menu somewhere?
