Preserve query params for affiliates

Feature request: Preserve query params through affiliate referral redirects (deep linking).
Right now, an affiliate's referral link redirects to the program-wide Website URL and drops any query string. If I append &niche=XXX to my referral link, the click records fine, but the param doesn't survive to my site; the visitor just lands on the bare Website URL.

Use case: I run one product but several niche landing pages (each with different audiences and copy). My affiliates serve different audiences, so I'd like each to send traffic to the page that best matches their audience.
Today, every affiliate has to land on a single URL, which costs conversions.

The ask: Forward unrecognised query params from the referral link to the destination URL. Attribution shouldn't be affected at all; the ref cookie is already set on Creem's domain before the redirect fires, so the params are pure pass-through.

Bonus: this would also let affiliates carry their own UTMs through, which is a common request for campaign tracking. Alternatively, a per-affiliate destination/deep-link override in the Affiliate Hub would solve the same problem.

Thanks!
