I just came across nofmultipars (which is great for splitting frames across pages, unlike a simple framed). Is there an equivalent for floats?

The MWE would contain

\startuseMPgraphic{mp:textFrame}
begingroup;
path p ;
for i = 1 upto nofmultipars :
p := (ulcorner multipars[i]) -- (llcorner multipars[i]) -- (llcorner multipars[i] xshifted .25cm) -- (ulcorner multipars[i] xshifted .25cm) -- cycle ;
fill p withcolor "darkgreen" ;
endfor;
endgroup;
\stopuseMPgraphic

together with

\definetextbackground
[exampleFrame]
[
mp=mp:textFrame,
location=paragraph,
]

Assuming I have between \starttextbackground[exampleFrame] and \starttextbackground[exampleFrame] also a figure in addition to text paragraphs. Would it be possible to also draw a rule next to it?

Best regards,
