Repeated Citations - suppress Ibid. for Series

Hi there, using Endnote X7.4; MS Word 2007; Windows 10.

I am having a problem with Ibid. showing up for citations where the Series is repeated, but not the Title. For example, Citation 1 might be from

Kevin Jones, The Way of Mystery, JSNT [this is the series name] 15 (London: T&T Clark, 2005)

Citation 2 might be from:

Peggy Smith, The Wonder of Style, JSNT 275 (London: T&T Clark, 2014).

These are 2 different works. However, Citation 2 is showing up as 

Peggy Smith, _The Wonder of Style_ibid. 275 (London: T&T Clark, 2014).

I realize that this is connected to “Edit Output Style,” particularly “Repeated Citations” under “Footnotes.” The problem is that the Series title is stored in the “Secondary Title” field, and “Secondary Title” apparently triggers the ibid. There is a checkbox that says “Replace only the secondary title,” but this is precisely the opposite of what I want. I want Ibid. to show up for a repeated  primary Title, but not the  Secondary

Is there a way to do this? Thanks & regards
