My question involves bankruptcy in the state of: Utah

I am in the process of trying to decide if Chapter 13 Bankruptcy is right for me.
My current income shows I would qualify for the 3 year repayment plan.

Am I allowed to voluntarily choose the 5 year plan? The reason is I have a secured loan on a property I need to catch up and I can only do so if I have the full five years to do it.
