Nested Sequence - Audio Consolidation Not Working

[btangonan]

In Premiere Pro 15.0 (build 41) when I try to drag a nested sequence into an existing sequence, the audio drop in as individual tracks rather than as one consolidated audio track.

This used to be my hack for nesting audio to be able to manipulate the entire group of tracks as one (for example, to add effects globally to them). Anyone know a different method?

Probably the "nest or not" icon is grayed, so "inactive", and not blue.
