Fastest way to export out multiple marker ranges from a long audio file

I record music performances just about every weekend. They are typically 2-3 sets of 1.5hrs each. After mixing, I need to chop up the stereo file to separate about 40 songs and export them as mp3 files. I have a process for this that is slightly tedious, but I've gotten pretty quick with it. This is typically rock music, so it's pretty easy to visually see the start and end of songs which helps a lot.

After a recent Audition update, I noticed that every time I create a new marker range (using the "m" key shortcut), the selection area snaps all the way back to the beginning of the file - it used to stay in place. This makes me have to drag/scroll all the way back to where I left off in order to create the next marker range as opposed to just scooting to the right a little bit. 

First question: Is there a setting somewhere that will allow me to revert back to Audition's previous default where it would level the selection area alone as opposed to snapping to the beginning of the file after creating a new marker?

Second question: In general, is there a faster way to accomplish my goal here? For example, is there a shortcut where I could hold shift + the back arrow key + something else to create that selection range between the cursor and the end of the previous marker so there is less dragging all over the place and snapping to the end of the previous song?
