Perhaps:
\setuppagenumbering[alternative=doublesided,location=bottom]
\startsetups chapter:headings
\doifsomethingelse{\structureuservariable{custom}}
{\setupheadertexts[RI]
[Prefix:
\structureuservariable{custom}]
[Prefix:
\structureuservariable{custom}]
[VO]}
{\setupheadertexts[RI][RO][VO][VI]}
\stopsetups
\setuphead[chapter]
[style=\tfa,
after={\blank\setups{chapter:headings}},
]
\starttext
\startchapter[title=Nothing special]
\dorecurse{10}{\input knuth\par}
\stopchapter
\startchapter[title=Something special][custom={Hi there!}]
\dorecurse{10}{\input knuth\par}
\stopchapter
\startchapter[title=More nothing special]
\dorecurse{10}{\input knuth\par}
\stopchapter
\startchapter[title=More something special][custom={Bye Bye!}]
\dorecurse{10}{\input knuth\par}
\stopchapter
\stoptext
