Exporting audio with markers button is greyed out.... ANY HELP MUCH APPRECIATED!

Question

Hello
so, background to the story. Now peak pro is defunkt on OSX I am trying to use Audition to create cdmasters. The idea being I will compile the album in audition, export wav files of each track including gaps and compile DDPi master in Sonoris DDP creator. Should be fine but quite a few limitations I've found already in audition.
1)Main question is this. Exporting tracks. I have compiled and added all the markers in to a 30+ track cd. I've exported whole thing to a single mixdown that includes marker but the 'EXPORT AUDIO OF SELECTED RANGE MARKERS TO SEPERATE FILES IS GREYED OUT' even if i select everything....
2)In multitrack mode, if you want to move one clip in the middle of the sequence, is there any way to select all the clips in all the following clips so that they all slip back together. I know you can zoom out and select everything but that is very boring especially when you have loads of tracks and if some are only a couple of second long soundbytes. In SAdie and Peak Pro it was very easy to set this function.
3)Moving markers. if I am moving a number of tracks is there a way of selecting and moving the relevant markers as well ? At the moment it seems like I'd have to select all clips in the boring zoom out method and then move each marker individually? Surely not...
2) & 3) are very annoying when you only want to move one clip by a few frames or seconds.
Any ideas folks ? Like i say uestion 1 is most pressing!
Thanks in advance

Answer 1

thanks guys, all makes sense, really appreciate it.
I will try the merging out. I was in a hurry to get a CDREF out so ended up just exporting the compiled album out as one wav from audition and adding PQ points in Sonoris. Not ideal especially as running order etc is bound to change. 
I can't recomened Sonoris DDP creator enough, fantastic program and very reasnably priced. I have Soundblade LE as well but find it too clunky to bother learning, its one of the least intuitive audio programs I've ever come across.
Maybe Audition and Sonoris should team up, if you could add PQ points into audition it could become the best OSX option for compiling cd masters.
Did you have any thoughts on questions 2)&3)
