[NTG-context] changing the symbol used in \footnote{}

I want to use the crucifix symbol as a footnote symbol on the title page of a book. I don't want this to increment the footnote counter. The best I can do is: \setupnotation[footnote][way=bypage, state=stop, number=†] but this does not produce any symbol at all. If I do: \setupnotation[footnote][numberconversion=set 2] then I get an asterix, not a crucifix, and I don't know how to prevent or otherwise reset the footnote counter for subsequent footnote numberings.
