Print widget that prints All

I need a print widget that allows the user to select All slides, rather than have to select each individual slide in a simulation. Some of my simulations are 100 slides long. Instead of having them select all 100 slides which is very tedious, I would like them to be able to click one Select all button and then click Print.

The existing Print widget only gives the user the option to select slides one at a time.

Does anyone have information on how to achieve a print all button, or does this widget exist somewhere?

Thank you all!
