DCP EXPORT PREMIERE PRO

It does look like there are 2 2K options for exporting a DCP.  Not sure what's involved in the workflow in Premiere.  Frankly, everytime I've needed to deliver a DCP, I've gone to a facility with extensive experience in exporting DCP's and then if possible screened at the venue ahead of  the showing.  Most theaters and screening rooms request (if not require) the hard drive to be delivered in a specific type of sled and there can be issues with the audio configuration, particularly if you don't have a surround sound mix.     In one case, the post house had used a 23.976 audio file with a 24 fps video file with serious audio drift within a few minutes...  

If you twirl down the format section in the export settings you might find what you are looking for.
