[HELP] A problem of deck construction

Could any one help me to solve this problem please?
I want to edit adeck in the directory DATA_DLC_1111, and I planed to add the card "KOR_DUELIST" to it. But the problem is that the card "KOR_DUELIST" is in the directory "DATA_CORE" and not available for the 1111 directory.
Or is there a way that the cards in "DATA_DLC_1111"
and "DATA_CORE" can be merged together?
Thanks in advance.
