Changing the order of crossreferences in biblatex footnotes [duplicate]

Question

I'm trying to use biblatex-dw and the crossref functionality to make my bibliography more structured and easier to edit. I'm using the mvcollection, collection, and incollection types for the inheritance/tree structure. My problem is that when I define things as in the MWE below, the footnote comes out wrong.

What I want to achieve -- but only for the archival document types -- is to organize the data into a hierarchy, starting with the most detailed (i.e. the specific document) and ending with the leaste detailed (i.e. the archive institution where the archive is situated):

document - volume - archive - archive institution

Therefore, the date would look strange at the end of the line as it refers to the document and not the archive institution. I think it looks much better if the data is clustered. But for normal references like books and articles, I agree the default biblatex ordering is great.

See image example below.

Update: I also tried this with biblatex-chicago and the same thing happens there.

\documentclass{article}
\usepackage[backend=biber,citestyle=verbose-ibid,style=footnote-dw,autocite=footnote,idembibformat=dash,idemtracker=false,pageref=true,xref=true, date=iso8601]{biblatex}

\begin{filecontents*}{refs.bib}
@mvcollection{MA,
    title = {Museum archives},
}

@collection{ClockExhib,
    crossref = {MA},
    title = { Clocks Project},
}

@incollection{foo,
    crossref = {ClockExhib},
    author = {Committee},
    title = {Meeting notes},
    volume = 1,
    date = {1979-11-19},
}

\end{filecontents*}
\bibliography{refs}

\begin{document}

This is a document.\autocites{foo}

\end{document}

I want to change the order of the details (and as a bonus also learn how to change the field separators...commas, dots, or whatever).

Any ideas would be much appreciated. By the way, I really want to stick to biblatex-dw.
