I want to change the way Piwigo creates links to albums - something like a new part to make_section_in_url() or make_index_url().

I've looked in [Github] Piwigo file tools/triggers_list.php but don't see an extension point that looks relevant.

Is their a way to do it, or is hand-patching Piwigo the only way to do this ?

I'm beginning to see why Piwigo doesn't have nice looking SEO URLs... but it has to be fixable.
