Changing Access_log Filename In Logrotate

how to rename access logs according to Week Number?

I notice that 1&1 do this, producing a file like "access.log.31.gz".
I'd like the access log to be in this format: access_log_[domain-name]_[Week-Number].gz, or if domain-name is not possible: access_log_[Week-Number].gz

Here's my current logrotate script for access_log:

Code:
/home/default/muro.co.uk/user/logfiles/access_log {
missingok
rotate 8
weekly
postrotate
/bin/kill -USR1 `cat /var/run/httpd.pid`
endscript
}
