Hi Mark,

Good to hear the if/else model suits you!

All the macros are tied to each and every message, and that's by design:
routing is done per message. If you want something tied to a destination,
all I can suggest is to set it as close as possible to that destination.
For instance, you can set it *in* the destination as follows:

    destination d_foo {
      channel {
        rewrite {
          set("my_static_vaule", value("MY_STATIC_MACRO")};
        };
        destination {
          file("/path/to/dest" ...};
        };
      };
    };
