Split cell into multiple pages

I have been reading the manual and made some tests wit longtblr and some other options, but not sure if it can be done with tabularray, or other table packages.

Use the next example:

\documentclass[11pt,a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage{blindtext}
\usepackage{tabularray}
\UseTblrLibrary{varwidth}
\SetTblrOuter{
    long,
    label=none,
}

\begin{document}

    \begin{tblr}{
        colspec={X[j]X},
        hlines,vlines,
        measure=vbox
    }
        Column 1 & Column 2 \\

        \blindtext[1] & row 1 \\
        \blindtext[1]  

        \blindtext[1]
            & row 2 
        \\

        \blindtext[1] 

        \blindtext[1]

        \blindtext[1]

        \blindtext[1]
            & row 3 
        \\
    \end{tblr}

\end{document}

Can the row2 and row3 be "splited" (or "breaked" automatically) to occupy multiple pages?

The idea is similar to what tcolorbox does with the option "breakable=true", but with a table's cell. Example of tcolorbox:


\documentclass[11pt,a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{tcolorbox}
\tcbuselibrary{many,breakable}
\usepackage{blindtext}

\begin{document}
    \begin{tcolorbox}[breakable=true,enhanced jigsaw]
        \blindtext[7]
    \end{tcolorbox}
\end{document}
´´´

Thanks for this great package!
