Marketing Tool For Merch By Amazon

We all know how marketing is important and we all can see that merch has yet to get a good marketing tool that would help sellers/marketers.

To understand what I mean better, there are tools for Amazon KDP like Publishdrive where authors can split royalties with either co-authors or people helping with the marketing of the books. Now the royalty distribution is not 100% automatic and I believe there is no way to do that on KDP or even merch, but the website does count the sales + each contributors percentage of the total royalties.

Something like this for MBA would be really helpful especially when working with influencers on long-term promotion plans for MBA products.

What do you guys think about this?
