Bing Custom Search: How can I include subpages for links deeper than 2 subpages?

Question

I am working on implementing the use of Bing Custom Search into my Copilot bot. However, when I try to add a link with more than 2 subpages, I get the message "Including Subpages is not supported for entries deeper than two subpages." Is it possible to simply trim off the end of the link until I get to two subpages in the link and use that?

If that method won't work, is there anything I can do with the Bing Custom Search API to allow or workaround the limit of two subpages? I have development experience so I am not intimidated by any exploration, coding, or research that comes along with this route.

If there is another workaround that you have used and have had success with, I would love to hear about it. Any help on this topic would be greatly appreciated.

Here is an example of a link that had more than two sub pages not being allowed to include subpages:

Here is the same link trimmed down to fit within the two subpage limit:
