Impress - script loop slideshow

Hi, is it possible to loot a slideshow using a bash script?
Now I use this command:

soffice --norestore --invisible --show Presentazione.pptx

Presentazione.pptx in powerpoint has a loop slideshow but in impress not. Is there a way to set it in loop by script?

I think you need to open the pptx, set the time for all slides for automatic change under slides change, then set under presentation settings “auto” with the time delay and save it as .odp in order to have the slideshow automatically show. I am not sure it can work with the pptx file.
I can only give you the menu item in italian since my copy is localized.
