\titleaddon equivalent for \publisher

Question

I am using biblatex with biber as backend. For displaying a text after the title field, there is the titleaddon field. Is there also an equivalent for the publisher field, which can be used to display a text after the publisher name? If not, is it possible to define a custom field? I would also need such an additional field for after the journal field in articles (not italic) and the school field for phd theses.

I use the Chicago citation style. Here an MWE:

\documentclass[12pt]{article}

\usepackage{csquotes}
\usepackage{polyglossia}
\usepackage[notes,natbib,isbn=false,backend=biber]{biblatex-chicago}  

\setdefaultlanguage{english}
\nocite{*}
\addbibresource{samplebib.bib}

\begin{document}
\printbibliography
\end{document}

And the samplebib.bib file:

@article{smith1999,
    author = {Peter Smith},
    title = {Article Title},
    year = {1999},
    journal = {Journal Title ADDENDUM NOT ITALIC},
    volume = {5},
    number = {4},
    pages = {119 - 145}
}

@book{smith2000,
    author = {Peter Smith},
    title = {Book Title},
    year = {2011},
    volumes = {2},
    address = {New York},
    publisher = {Publisher PUBLISHER ADDENDUM}
}

@phdthesis{smith1995,
    author = {Peter Smith},
    title = {PhD Title},
    year = {1995},
    school = {School SCHOOL ADDENDUM}
}

Thank you very much!

Answer 1

Normally this would be as easy as creating a new .dbx, declaring the new fields there, loading it and then using the new fields in the respective macros. See Add field “tome” to biblatex entries.

With biblatex-chicago the number of macros to modify can be quite large, and the macros may contain quite a lot of lines.

Furthermore, biblatex-chicago does not allow for the datamodel option. This complicates things. We need to copy what the wrapper package biblatex-chicago.sty does in the preamble.
