I don't want to talk about the usefulness of doing so here, just the fact that you literally cannot do so. Is there some way to mark a checkbox so that the AI will send you condottieri deals even if they think an AI in your position would never accept? The current system is really good for a player who doesn't want to be spammed to death with terrible deals and misclick into a bankruptcy, but sometimes I'd like to be able to take out a stack of loans for some overpriced 20k foreign troops. The only time an AI ever offered me condottieri it was free; this AI had a track record of showering me with gifts and subsidies and this was just one part of that.
