Is there any way of setting the language of a Powerpoint presentation to be different from the system language?
I found ways for changing the language of currently existing placeholders (and also VBA code for changing all text). E.g.
How do I change the language of all Powerpoint slides at once?
Change the spell-checking language on a PowerPoint presentation
and many other links from googling.
But these do not act for anything to be inserted in the future. Thus, I might use this after the presentation is finished, but it is still a workaround, and it is incomplete, as I might forget applying it after finishing, or someone else might not do it in shared work.
EDIT PS: This is a follow-up question for
