Pro Tools allows you to copy your main fader mix with "Copy To Sends". This means you can get up a quick mix during a recording session and then copy it to the Send you are using for the headphone mix.
Here's a video which outlines the process.
Would love to see this feature added to S1 v. 3.x

Damblack commented and I received notification via email. I had forgotten about posting this question/comment.
Just after posting my question I discovered that there's an even better feature in S1 to address cue mix. They already have a cue mix available so you don't need copy to send. However Damblack's comment suggests an opportunity for Presonus to add an additional feature to their already superior workflow of having a cue mix available and already 'switched on' so you don't' have to create it. (See his next comment).
