Hi everyone, I am new here and I am wondering how to save "extract ions" into batch in chemstation.

When I was scanning samples with LCMS, I entered three different ion molecular weight number into one SIM signal. I know I can using the File--> Extract Ions... button to extract one of the three. But I don't know how to save it. When I move to next sample and then come back the extracted ion chromatography is disappeared. If I hit the batch save button chemstation tells me the chromatography is not generated by batch review so it can not be saved.

Is there any way to save it?

Thanks
