Limit product visibility based on user login or group code

[JKCustom]

Hi,

I'm looking to see if there is a way to allow groups to come to my website enter a code or search for their group and then only see the items that are being sold as apart of that group. Sort of like if it was a fundraising initiative and a customer looks on our site to find their school and therefore will be able to see only the items we are selling for their school almost like a print-on-demand deal. 

Not sure if there is already an app to do this.
