How to customise the 404 page non members get?

Hey there,

When a page is accessible by a certain group only and non members of this group get to it, they get a 404 page. I’d like to be able to customise this page to let them know this is for XXX members only and prompt them to buy/log in (I’m using the Groups plugin together with the Groups for Woocommerce one for buyers of on-demand video to be the only ones to have access to said videos).

Where can I do that – without changing the other on groups-related 404 pages site-wide?

Thanks a lot!
