by default, please have 6 Take Action covers show for L and XL screens
by default, please have 4 Take Action covers show for M screen

if it's possible to determine this on a page-by-page basis, I would like to make all available covers appearing on the [Act|https://dev.p4.greenpeace.org/international/act/|https://dev.p4.greenpeace.org/international/act/] page for L and XL screens

thanks!
