Adding Series Information to Spine Labels with "Macros" Does Not Include Volume

[John Yorio]

Evergreen 3.6

In an attempt to add series info to spine label, I added:

{{col.c ? get_bib_for(col.c)['series.0'] : ''}}

It works great in that it brings in the Series Statement but there does not appear to be an equivalent way to bring in the Volume.

I had hoped the 0 could be changed - as if it were an index of the subfields in the 490 or 830 for example, but it does not appear to function as such.

It would be helpful if there was a way to bring in the series volume info.

FWIW, I also tried ['call_number.record.series_field_entries'] but that didn't return anything (but no error).
