I would like a LUA script, so that with the help of it the thing in the map is shown item in the first slot. It's a really?

You mean using -itemid without insert jj cp ?

Yes, can to do it? It's a can be lua script, trainer or dll.

yes , its possible in theory
But mostly it will not same the itemid you use in jjcp because war3 using 4 bytes in little endian so revert the result which make hard to read
I havent seen one , still prefer you insert the jjcp than find it
