Adjusting protein and carbs

is there a way to adjust MFPs daily requirement for protein and carbs? Although I dearly love my carbs, I think 55% carbs a day isnt the best plan for me. I would like to adjust the carbs down and the protein up...consistently...but I can't figure out how to do that in the program settings. By no means do I want to eliminate carbs, but lower them to maybe 40% and increasing protein by whatever factor then gets me to 100%, realizing it's not an even swap of numbers due to nutrient requirements.

Thanks for any guidance for this newbie!
