Add User To Display On Product From Certain Role

Hi there,

I would like my vendors to be able to select from a certain role type (eg Producers), via a custom field on the ‘add product’ page in vendor dashboard, to be able to display that Producer’s own user page as a linked avatar on their product page, has this come up before?

To make sure I do a good enough job of explaining what I mean:

If half of my users were ‘vendors’ role and half ‘Producers’ (I need Producers as a user role, but it’s relevant to display this info as link from the product page also, because it helps to explain the value of the listed product).

So I would like the vendor role who lists the product in the front end dashboard, to be able to choose these producers from all available under that role. I need the vendor to have a field where they can type into a multi-select box which pulls the data up from role type ‘Producers’ in the user database, and add each relevant user they wish to show, and then click save to add the selected users of Producers role to display on their product page with a linked avatar.

Has anything similar come up before?

Is there a plugin that could help do this or a starting point?

Kind regards
