David,

Though I have never tried myself, the online documentation tells us
that, "[...] it is possible to change the precedence of an operator
through the use of the TagBox option SyntaxForm. [1]" There are more
information in this advanced tutorial [2]. (Both relevant sections are
the last one of each tutorials, near the bottom of the pages.)
