syntax for checking multiple tables in a single mumble restriction type?

[jasonsu]

In my

  smtpd_helo_restrictions

I've had a 

  check_helo_access lmdb:/path/table

I want to add a 2nd table to check.

Is the correct usage for multiple tables for the same check type to use 2 
separate instances, e.g.

  check_helo_access lmdb:/path/table1
  check_helo_access pcre:/path/table2.pcre

or in one line

  check_helo_access lmdb:/path/table1,pcre:/path/table2.pcre

?

I'm sure the docs mention it somewhere, I just haven't search/found the right 
terms and location yet :/

Thanks.
