Work Experience Approval

I just reached 4 years of full time work experience and am submitting my application this week. I spent my first 3 years in an entry level rotation program. Has anyone submitted work experience from a similar program? My issue is that my rotations were mainly through capital markets groups with the exception of my first which was strictly a financial reporting role. I can either lump the whole 3 years into one description, and only briefly note the reporting work, or I can list them one by one in which case the reporting role will most likely be declined. Clearly I prefer the first option but also feel that it’s slightly misleading. Any advice?
