Nothing so far. I think theres a huge opportunity for an app developer to come up with an app that can offer this service. I know Id pay for it. Similar to a slideshow on the home page, you can have "x" number of potential mini banners that populate on a collection page. They could be random or you could specify specific banners to only populate in specific collections.
App community, get on it!
Hey @brennonk, not sure if you've found a solution here, but I might be willing to build something like this for you.
How much would you be willing to pay for an app like this?
