Displaying fonts when opening Powerpoint files in Impress

I often view Powerpoint presentations that I receive from clients.
If I open a Powerpoint file in Powerpoint, I can get a list of the fonts that have been used in Properties>Content. Using that information, I can make sure I have the correct fonts installed to display them correctly in Impress.
However, if I didn’t have Powerpoint, is there a way that I can get this font information using Impress?
