Hello RobertWA,
I'd never used the titling function in the slideshow module of PhD (I usually process the images in PhD then build the slideshows in PD), so thanks for raising the question.
It seems like those titles are generated dynamically & cannot be saved as separate files. They do, of course, display in the produced video. So - that's a no to (a).
Question (b) is a no, too. There's nowhere else in PhD that titles can be constructed or saved.
Were you to take a screenshot of the title in PD (or whatever NLE or media player you use), you'd have an image file which could be used in subsequent productions.
My view would be that constructing a title page in other software & saving in an image format would yield far superior results.
