Can I add query parameters to a link to a pendo URL?

I'm trying out the URL unfurling Slack extension and it's great, except that I can't seem to figure out how to customize the results based on date range or segment.

For example, we have a segment called "Customers only" and I want to send a link to a colleague over Slack for usage of a given page with that segment for the last 90 days. I can't seem to make that happen. When I send the link, it's always for "Everyone" and the "Last 180 days".

I feel like I'm missing something obvious, but I couldn't find the answer by searching the community or help - maybe I lack the right vocabulary for my request.
