Assigning global access rule for a directory's sub-repositories with gitolite

Question

I am organizing every user's repositories under directory named as the user's alias; For example if i have a user named dariush and he has 3 repos named repo1, repo2 and repo3.The directory structure of dariush's repos will be something like below:

~/repositories/
      |_ dariush
            |_ repo1.git
            |_ repo2.git
            |_ repo3.git

The topic which discussed here suggests that for every each repository of our example user dariush above, I define an access rule in gitolite-admin/conf/gitolite.conf as below:

repo dariush/repo1
      RW+    =   dariush

repo dariush/repo2
     RW+     =   dariush

repo dariush/repo3
     RW+     =   dariush

OR

@dariush_repos = dariush/repo1 dariush/repo2 dariush/repo3

repo @dariush_repos
     RW+     =   dariush

But it makes sense if i want to try to use regex like below to assign access rules

repo dariush/.+
     RW+     =   dariush

which means for every repositories under directory ~/repositories/dariush apply the following rules.

But it is not working!!

My quesions

1. Is it possible to do such thing i.e using regex like repo dariush/.+ to define rules, if so what am i doing wrong?
2. If the question #1 is not possible is there any other more convenient way to accomplish such matter?

Thanks in advance.
