Hosts machine names used in Display filter macros?

I have a hosts file with several IP addresses mapped to strings like VCG, VS, and VSTG (which are my server names). I have many display filter macros with these same IP addresses hard-coded into the macros.

Is there a way to use the same strings from my hosts file in my display filter macros? Thus eliminating the need for the hard-coding of the IP addresses?

Thanks.
