I would suggest you to use the �VI Library Manager�� from the �Tools� menu. Using this, you can convert directories into LLBs and vice versa. You can then manually add the VIs or simply create the whole data.llb file.
Another option is to use a dummy VI as a wrapper, put all the wanted VIs into this wrapper. You can then place the wrapper VI inside a dummy state in a Case Structure inside the main VI. Even though the case will never execute, the VIs will still be included in the LLB.
I hope this answered your question.
