Seeking a commission or referral app that automates cash payments with a drop down list of referrers

[LibertyJason]

Hello,

I am aware of many of the most popular commission, affiliate, and referral apps on Shopify, however I haven't noticed if any apps that automate pay-outs but INSTEAD OF or IN ADDITION TO using discount codes or referral links, it allows the referrer or affiliate to be chosen from a drop-down list in the cart, or on the product page.

Any leads by anyone in this fine community? Thank you!
