Apply multiple spot colors to specific objects with data merge

I am working on a design where a client wants a spot color chart. There are 2000 individual objects where each object needs to be a specific pantone color. On top of the object will be the pantone color. Is there a way to run a data merge of the spot color number to also apply the spot color to the object? Is there a way to apply a different spot color to each object automatically without selecting the object and selecting the spot color? Just looking to simplify the the process as selecting 2000 objects and spot colors will take forever.
