Mp ids missing

Hi,
Im new at MP, Im trying to obtain some structure information about some compounds, but theyre not on MP. I was wondering what options I have. It seems that structure predictors takes a while, and its not efficient when dealing with many compounds. Probably I can find some CIF files on Crystallographic Open Database, or in some papers, how do you think I could integrate this information to MP and get structure information?.

Any help is appreciated
