Hey @cacpro,
Thanks for reaching out to us! Interesting questions here…
Let me recap a bit, you need to add a page in the following URL: http://site/events/past-programs/? In that case as you say the user will be redirected to the past events listing.
Running a quick test locally I can see this only happens if the page slug actually starts with past, but if you change the slug to something else like the-past-programs then no redirection will happen. Do you think that might be an acceptable workaround?
Please let me know about it,
Best,
Nico
