Open File from Previous Folder Location

In my previous Draftsight installation when I clicked Open it would default to the folder that I had previously opened a Draftsight file from. In Draftsight 2021 it would appear that I can only set one default file open location. This is not practical as I am a contractor with multiple file locations for multiple customers. I am currently wasting time navigating to the relevant file location.

Is there a setting that I have missed that will enable Draftsight to default to the previous file opened folder?
