[Exim] making one rule out of two

This is in an RCPT TO ACL.
Can I condense these two rules in one?

  warn     message    = X-WhitelistedRCPT-nohdrfromcallback: Yes
       condition    = ${if exists {MAILMAN_HOME/lists/${sg{$local_part}{(.*)-bounces\+.*}{\$1}}}{yes}{no}}

  accept  condition    = ${if exists {MAILMAN_HOME/lists/${sg{$local_part}{(.*)-bounces\+.*}{\$1}}}{yes}{no}}

How about those:

  warn     message     = X-WhitelistedRCPT-nohdrfromcallback: Yes
       local_parts     = abuse

  warn     message     = X-WhitelistedRCPT-nohdrfromcallback: Yes
       local_parts     = postmaster

I know I can put both in a file on disk and include that. Is there an other
way to say something like
local_parts = postmaster or abuse ?

Thanks
Marc
