Merging molecules (Data image)

Hello,

I have a list of molecules I want to merge according to a property value.

When merging it keeps only one molecule structure (Data image) but unfortunately not the one I want. Is there a way to express which one to keep (according to property for example)?

What is a bit strange is I tried to circumvent this problem by using the "standardize molecule" component with the option remove molecule and afterward using a "molecule from SMILES" using the other SMILES field but it still gave me the other SMILES code structure!

Thanks for your help!
