local-pref is the main outbound control tool.
As always with BGP (and other protocols), it's not possible to
specify things like "x% via there, %y via yon", instead you have to
think of useful ways you could discriminate between routes (which
depends on your setup/topology), apply, observe, think again and
refine, apply, etc..
