You can add a new store_id_map directive. I do not think it should
depend on store_id_program actions. The two options do not even have to
be mutually exclusive: if store_id_map does not match, check
store_id_access.

  store_id_map <filename with a regex map> acl1 acl2 ...

If you do something like that, I urge you to revise the current regex
map file syntax used by a popular StoreID script to allow for comments
(if not already allowed) and to contain complete substitution patterns
instead of space-separated from/to tokens:

    # comment
    s/replace this/with that/flags
    s_at_can use custom delimiters and other regex features_at_as needed_at_g
    ^this line is an invalid line example$

To minimize confusion, you can even require that the map file starts
with some well-defined prefix. For example:

  #Store ID Map
  #Version: 1.0

This approach will allow this feature to evolve as needed.
