Asana2Go works in Chrome, MS Edge, Opera, and Brave.
The Table - Interactive format will show one column with the values of every custom field on the task.
To have a single column, you’d need to create a custom report which requires knowledge at the level of someone who maintains a website (or can fake it by learning from example).
In this post, the very last link is an intro video to Asana2Go. The last 2+ minutes demonstrate starting with an existing format and making a change to it. That’s what you would do, and use {{lookup custom_fields_simple 'MY CUSTOM FIELD NAME'}}
