[NTG-context] Italic, captial Greek letters (with Latin Modern)

Hello, if I understand Latin Modern correctly, it contains the \Psi both as upright and as italic version (CM has only the upright version). How can I get the italic version? It did not work this way: \usetypescript[modern][texnansi] \setupbodyfont[modern,12pt,ams] \starttext $\Psi$ \stoptext Tobias
