Customizing biblatex lists of abbreviations: separate lists for different authors

Question

Is it possible to use biblatex's \printshorthands to achieve the following two effects?

1. I would like to have three separate lists of abbreviations, for the three authors whose works are most frequently and repeatedly cited.
2. I would like to have each abbreviation give only the title of the work and the date.

@moewe's answer gets me very close to what I need. Here's an MWE based on that answer:

The style I'm following requires the list of abbreviations to come before the TOC. I've tried to adapt moewe's answer by a new \chapter*{Abbreviations}. A couple of problems with the result:

1. The abbreviations for Frege's works and for Russell's works each start on a new page, after the introductory note that the full details are in the main biblio.
2. I still need a separate list for other authors, here Bradley and Korselt entries.

Answer 1

It is possible to filter certain names, for example with my solution from Add arguments to \declaresourcemap based on Audrey's solution to biblatex: filter out publications from a specific author in the references dynamically

\newcommand*{\generateauthorcategory}[3]{%
  \DeclareBibliographyCategory{by#1}%
  \DeclareIndexNameFormat{cat#1}{%
    \ifboolexpr{test {\ifdefstring{\namepartfamily}{#2}}
                and test {\ifdefstring{\namepartgiven}{#3}}}
      {\addtocategory{by#1}{\thefield{entrykey}}}
      {}}%
  \AtDataInput{\indexnames[cat#1][1-999]{author}}}

\generateauthorcategory{elk}{Elk}{Anne}
\generateauthorcategory{kant}{Kant}{Immanuel}

But it is also possible to do that with keywords manually, or automatically. See biblatex: separating publications of a specific author in the bibliography. We could also use hashes to filter the entries, that would be more accurate in cases where you have authors with very similar names, but the general procedure is bit more awkward Highlight an author in bibliography using biblatex allowing bibliography style to format it.

Of course you will still have to specify the names of the three most frequently cited authors, they are not determined automatically.

With

\DeclareBibliographyDriver{shorthand}{%
  \usebibmacro{title}%
  \newunit\newblock
  \printdate}

you only get title and date for the list of shorthands.
