Enable editors to crossfade nested sequences in Audition

A common workflow (at least for me):

• I cut together a sequence of clips in Premiere.
• I need to apply video transitions to multiple layers of video content, so I nest the layers by selecting them and right-clicking to select “Nest...”
• I now transfer the sequence to Audition to do final audio.
• I can’t apply crossfades to nested sequences in Audition.

The process of nesting them in Premiere removes their handles. The clips in the nested sequence have handles, Audition should be able to “see” that. I shouldn’t have to do any additional preparation in Premiere or keyframe the fades in Audition to accomplish this.
