I used to be able to remap missing fonts onto available fonts. Once set, this would happen automatically with every file I open. So for Instance when I opened a file that used Swiss721 it would use Helvetica instead.
It has been years but now using InDesign on a mixed network (Mac and PC) a lot of files go back and forth between machines. We have the same fonts installed on each machine but we have to go to Font Finder every time to tell InDesign to use Helvetica instead of [Helvetica].
Where is Font Mapping in InDesign?
