Increase The Number Of Selected Products

How to add others value after "100" to increase the number of products per page?

I need to add 1000 - 10000 - 50000.

Thank you in advance.

Would require code changes to links for "items_per_page" or a 'pre' controller to intercept the request(s) and reset the limit.

?dispatch=products.manage&items_per_page=1000
?dispatch=products.manage&items_per_page=1000

Hi, thank you!
