Double doors less than 4ft wide

[jamsdragon]

I have Home Designer Architectural 2014. I have an occasional need to design an interior double door that is less than four feet in total width (i.e. entry into a bathroom) with each door less than 24" wide, but have been unable to find any option on my software to make a double door less than 4' wide (it always shows it as a single door). It does not display correctly when I try to place two separate doors side by side. Any help would be appreciated!
