Copilot

In the training course we was shown how to use co pilot to automate agreements, feeding information into excel and putting it onto a word document. This was done for one legal entity and it works, however it doesn't seem to work for more than one entity as it gets confused and cant differentiate between which entity I want to include in the agreement. is there a better way of feeding information into excel in order to have the document addressed to more than one legal entity?
