title: Create foreign key without checking existing data
body: <p>This is a 2 part question.</p>
  
  <p><strong>Question 1:</strong> I am trying to create a foreign key on a table where I need to turn off the "Check Existing Data on Creation or Re-Enabling". I know theres an option visually but I'm looking for a way to do it programmatically. Is there anyway to do this?</p>
  
  <p><strong>Question 2:</strong> I have a code table and two tables A and B that need to reference that code table. I want to have these both referenced from a relationship table but I want to able to use the same column. Can I have 2 foreign keys pointing to the same column?</p>
