Resume formatting advice - how do you show two different IB positions at the same bank on your resume?

Would like to get some advice on how to best display two different investment banking positions within the same bank on my resume? For context, worked in a Diversified coverage group but recently got transferred into the M&A product group....was playing around with the formatting on the resume but looked odd to show two positions as resumes typically do given the firm title is the same in both cases. Any advice would be appreciated!
