analyze_ppt(input, output) function not finding all layouts

[NikoTumi]

Hi, I ran your function analyze_ppt(input, output) through a slide with set template that I was given.
I opened new file, set theme, saved and used as input for the function.
It finds the title page, which is under the theme name in power point. But it does not find the other slides that are for text and title only which are under another row in the new slides drop down menu in power point which are sub theme named MS_Template_External.
Is there anyway to get your code to recognize these other layouts inside the theme?
