I am setting up an A/B with a Redirect Offer, and A4T as the reporting source

The issue I'm facing is that the destination URL is not static, but the path must be changed and the possibilities are numerous

Original: mysite.com/apples/product/ OR  mysite.com/bananas/product

Redirect: mysite.com/apples-beta/product/ OR  mysite.com/bananas-beta/product

When using a redirect offer, I only see that there is an ability for a 1:1 redirect, and not an ability to make it dynamic. for example amending "-beta" in the path
