We have a pretty unique use case in that our "catalog" is largely record producers, but here's what we are doing utilizing the "Available For" and "Not Available For" functionality.
Created validation variable rules that are then applied as AVAILABLE FOR or NOT AVAILABLE FOR. Then based on those rules and the users applicability in them, they see the catalog cards only applicable to them when they're on our (please note CUSTOM) Service Portal.
This might be what you're asking, or might not. But taking a shot it could help.
Below image and script is from the Rule that only displays "Greater Asia" related catalog items to a user with a country in greater Asia. But in this case Greater Asia is in the NOT available for category so does NOT see this item.
Basically.... you can get creative.
//Validation Variables
var servicedByAPSSC = false;
//User Variables
var currentUserID = gs.getUserID();
var userGR = new GlideRecord('sys_user');
//Validate user record
if(userGR.get(currentUserID)){
// Check User is located in a Country Serviced by "APSSC"
if(userGR.u_country.u_serviced_by == 'APSSC (Greater Asia)')
servicedByAPSSC = true;
}
answer = servicedByAPSSC;
