I lived in another state for a few months more than once in a year. in "Your State Returns > Dates of Residency" page, it only allows one consecutive duration. What do?

For example, if I lived in my home state during the summer, but on campus in another state (grad student, non-dependent, older adult) for 4 months in spring and 4 months in fall, how do I enter that into the form? It only allows a single start and end date.
