[Help] S9 How to modify the monster summoned by sommoning scroll

I am using MUEMU IGCN s9 sever file.

The summoning items, like Titan's Anger or sommoning scroll, can sommoning a monster when drop it. I want to know wehter it is possible to modify the type of monster sommoned.

For example, Titan's anger can summoning Titan. If I want change Titan to Kundun (i.e. Summon Kundun when drop Titan's anger), which file should I modify?

BTW, is it possible to transplant this summoning scroll to S6 server?

Thanks in advace!!
