add attached data in bulk

Hi

we are doing the work that adding the same attached data information for many structures.I learned removing attached data function already existed in the Standardizer. is it possible to add the same data in bulk? could you tell me the command line for adding data? we would like to try it for more than one structure. additional, we also would like to learn how to get attached data information from a structure by command line

Thank you very much

Standardizer cannot add attached data to molecules, it can only remove it. ChemAxon's Java API or .NET API can be used to implement this functionality.
