Create hidden multiple choice question filled by embedded data

Hey mj_stoker,
You can create embedded data fields in top of survey flow(Refer below image):
You can pass these fields in a multi choice question and a simple JS(Refer below image):
Qualtrics.SurveyEngine.addOnload(function() {
jQuery("#"+this.questionId).hide();
  this.clickNextButton();
});

Make sure to make these choices by default selected. Hope it will work for you.

mj_stoker,
Here is an example where the region names from the contact list are in the field Region with the values Region1 and Region2. You can change those and add as many as you need. 1 and 2 are the choice ids of the regions in your MC question. This will work with single select or multi-select MC questions (i.e., supports multiple regions stored as 'Region1, Region2').
Qualtrics.SurveyEngine.addOnload(function() {
jQuery(this.questionContainer).hide();
var ids = {
"Region1": 1,
"Region2": 2
};
var qobj = this;
jQuery.each("${e://Field/Region}".split(", "),function(i,val){ qobj.setChoiceValue(ids[val],true); });
qobj.clickNextButton();
});

Thanks for suggestions everyone!
