Is there a cat food that combines the urinary so type food with a formula for sensitive stomach?

I have four cats, one has a sensitive stomach (throwing up anything that is not the vet brand sensitive stomach formula) and one that has stress issues that causes him to stop using the litter box and is on Urinary SO to help fight the accumulation of crystals. It gets expensive to have to buy two different cat foods and I wanted to know if there was one food out there that would cover both issues.
