batch merge pptx files into one presentation - Impress

I have a folder(Win10) that has ~100 individual pptx files in it. I want to merge them all into one master presentation. I’m new with LO so don’t know how. This may be very basic to some of you, but I’m having trouble doing it…

This may not exactly what you are looking for, but should give you a start. It is a bit dated, but worth while to try as much work has been done to LO since that post.
