Zorin 18 and DOS Support

Hi All,
I finally upgraded from Zorin 16.3 Pro to Zorin 18 Pro. One thing I really liked about Z16 was that when I double clicked on a DOS executable (usually GW-BASIC or Basica,) it would attempt to run it. A lot of stuff worked! Was that built in to Zorin 16? Does anyone know how I can activate or otherwise replicate this behavior on Z18? I have both DOSBox and Windows support installed. TIA!

I used FreeDOS on a thumb drive to update the BIOS on an old machine.
