A Style that writes into the preamble is impossible.
But there is a workaround: A separate document with just the "Preamble
Styles" that is exported to TeX and included from the main document preamble
with \input{thepreamble.tex}.
You could also file an enhancement request to bugzilla asking for a
"InPreamble" keyword (similar to "InTitle").
