Making direct offline processing actually useful

What is the point of direct offline processing, when you can’t easily convert the insert chain of a selected track to direct offline processing?

Basically, a way to effortlessly move your insert chain on a selected track from real-time, to offline processing. Like virtual instrument freezing, but for audio tracks. I tried to do this-this evening, and was confused that it apparently cannot be done (correct me if I am wrong).

It would be a nice feature, but you can also freeze an audio track.
