Improving API Deck Export: Custom Slide Master, Font Choice, and Theme Embedding Options Needed

Max J. -- Im generating decks via the API. We are purely exporting as PPT and then moving the PPT into a corporate template afterward. Issues are (a) decks have an underlying emplate that doesnt port to the corporate deck and (b) it's picking Inter as the font and it's not standard. Would be nice if I can specify (a) no custom slide master and (b) the font and (c) no embeded theme so the move to the corporate template is as clean as possible.
