[syslog-ng] Multiple rewrite conditions under 3.4.x

Hi all, Is it possible to add multiple rewrite conditions in syslog-ng 3.4.x like this: rewrite r_rewrite_set{ set("myhost1", value("HOST") condition(program("myapplication1"))); set("myhost2", value("HOST") condition(program("myapplication2"))); set("myhost3", value("HOST") condition(program("myapplication3"))); set("myhost4", value("HOST") condition(program("myapplication4"))); }; ?? Is this a good option or maybe a performance penalty?? Thanks.
