A better solution requires more information from you!
\definelayer[test]
\startsetups[test]
\doifinset{\pagenumber}{1,3,7,10}{\setlayer[test][x=3cm,y=7cm]{\ssd Test:
\test}}
\stopsetups
\setupbackgrounds[page][background=test,setups=test]
\starttext
\dorecurse{12}
{\def\test{\convertnumber{A}{\recurselevel}}%
\dontleavehmode\page}
\stoptext
