How can I use the field "Researcher Notes" in my output style?

There is also the field “Notes” which contains number of citations from the Scopus database. When I use “Researcher Notes” in my output styles (for BiBTex) with the line

| focus = {Researcher Notes},

the output is focus = Researcher cited By 45

that means, the “Notes” part of the code refers to the Notes field, and I cannot get my info I stored in Researcher Notes.

What can I do? Is there a way for me to circumvent this hard coding inconsistency? I tried different ways to clarify that “Researcher Notes” belong together, but the “Notes” part always breaks through.

P.s.: that’s my problem after spending hours to manually transfer my multiple tags from 850 entries into the field “Researcher Notes”, because there is apparently no way to export tags (nor the rating).

I am not following the problem. Is this via connections or exporting and importing via filters? Can you do a global edit on a file before importing changing the tag to a single word?
