Custard Apple

Yes that's better than you! A little obscure though, don't you think?

So I've loaded an .eps containing many different logos on a transparent background. No matter what I do, when I select objects and make an artboard around a particular area, I lose the background transparency. The artboard always creates a solid white background.

Affinity Photo needs to ask at what dimensions to render the eps when it's imported, just like Photoshop does.
