Not really necessary unless you have a program outside of your geographic range that probably wouldn’t interview you if you didn’t rotate there. Also, if you’re wanting to go to an academic IM program you need to apply to more places... for reference I had a 235 and 569 on level 1 and a 255 and 779 on level 2 and applied to around 35 programs and only got like 11 interviews (granted 10/11 were academic programs but all were within the south/Midwest where I grew up).
