I have been querying agents that rep in the two genres I want to write in but I am finding some agents that only rep in one of the two that I would like to query.

Should I get the one agent in one genre and then either try to talk them into repping the other genre later, find a second agent in the other genre at the same time or get an agent and have them refer me to another agent for the other genre later or just keep limiting my search to an agent that reps both?
