Linux app - export collection - doesn't remember last used folder

I usually use postman on my mac but these days I’m working in Ubuntu 20.04. To keep my api collections versioned, i export the collections regularly to a folder that I then commit to github. My front end developers can then always access latest api docs. It’s a great system.

On mac, once i select the folder to export to once, it remembers it for all export functions thereafter. In Linux however, i have to navigate to the folder EVERY SINGLE TIME. I thought maybe setting the working folder would work but again in LInux i can try to set it to anything I want, it always defaults back to ~/Postman/files.

Help!

Ty!
