SLES7 (Suse 7.2) and runlevel

Hello! I have "strange" ;-) (for me) problem. I have several self written scripts in /etc/rc.d I linked them with ln to appropriate runlevel as I usually do on RH ( I don't like chkconfig). But I found that yast2 renames my link names from S20... to S00 or S01... How can I tell to yast to not do this? Thank you!
