Well, it's not a feature, but since the info is available, i can imagine
something like this:
Say that I patch a macro :
\unprotected \def\dolijstelement#1#2#3#4#5#6% pas op: wordt ook elders
gedefinieerd
{\doiftoclevelelse[#5]
{\def\currentlist{#1}%
\ifundefined{\??li\currentlist\c!huidige}\else
\doif{#3}\currentheadnumber
{\edef\currentlist{\getvalue{\??li\currentlist\c!huidige}}}%
\fi
\dodolijstelement\currentlist{#2}{#3}{#4}{#5}{#6}}
{}}
(this assumes a version where \currentheadnumber is known)
now we can define a fake list (since i can imagine that you want to set up
some layout characteristics)
\definelist [fakesection] [section]
\setuplist [fakesection] [before=\blank,after=\blank,color=green]
\setuplist [section] [current=fakesection]
\setupcolors[state=start]\setupinteraction[state=start]
\starttext
\chapter{test}
\section{test}
\section{test}
\section{test}
\placelist[section][criterium=previous]
\section{test}
\section{test}
\stoptext
We can have a vote for adding this feature -)
