Hello Laurinda,
Thank you for posting your query.
I would like to inform you that there is no option to enable “ignore paging” checkbox by default neither you can create a javascript for the same, however, if you want to increase the paging limit then you can do it from webparts ezEdit configuration under “Sorting/Paging”
However, I don’t think this will help you in the scenario mentioned by you, hence user would have to check the box every time manually.
Thanks,
Rachit
