Global Markup Cost Code

When a Global Markup is assigned on an Estimate and it is not distributed/hidden, it will then create that markup as its own line on the Prime Contract. When this happens the system creates a new JCC for that markup, which typically is not the cost code they want. So, can we add a field on the Global Markup where you select the JCC to assign so that when it creates the item on the Prime Contract it uses that cost code and not a generated one.
