Use Advance Expression to select multiple Values in VBS

Summary:

How can we use Advance Expression within VBS to select multiple values for a field?

For example - VBS only lets you default one selection but in this instance, I need to default 3 selections out of the list below.

So we need to be able to choose only 3 of our Legal Employers on the Job Offer, Create Requisition page and hide the rest.
