It seems that httpok cannot restart whole group defined as fcgi-program

Say, if I have defined it like this:
[fcgi-program:test-fcgi]
...

Then "httpok -p test-fcgi:*" or "httpok -p test-fcgi" do not seem to restart the group.
But if I list all fast-cgi processes one by one:
-p test-fcgi:test-fcgi_20 -p test-fcgi:test-fcgi_21 and so on - then it seems to work as expected

it would be nice if httok could restart whole group/fast-cgi as at once.
