Premiere Pro :: Analyze Content / Sequences As Well As Clips?

I recorded video on a Black Magic Cinema Camera (BMCC), which has legendary video quality but an awful on-camera microphone with tinny recording process, and recorded audio on a Zoom H6 which has great low-noise, more bits and greater sampling rate capability.
 
In Premiere I made a Sequence containing the video footage, then added the H6 audio and synchronized it by waveform to the BMCC's audio, which I subsequently muted.  I call this a Source-Sequence, as it is intended as a virtual source media item, to be cut into one or more Edit-Sequences (my term).
 
Not "holding my breath" but trying it anyway, in Premiere's Project/Bin pane, I selected that source-sequence then did RightClick > Analyze Content.  Teasingly, that option was not greyed-out.  However all options in the the resulting popup-dialog were greyed-out.
 
In this situation, to be useful, the speech analysis would need to be available to Sequences, not just to (Master) Clips.  Obviously one could render such a sequence to intermediate but that would waste time and disk space and would essentially freeze the state of the Source (e.g. including any sync issues that might be discovered later, or whole-source color corrections issues etc.).  If one subsequently altered that state, a re-render, re-link and re-analysis would be required.  If a Souce-Sequence were used instead, and no alteration had been made to the audio (or if user indicated "don't care"), then there would in principle be no need for re-analysis.
