How to enter extracurriculars


I am applying via AACOMAS this cycle and am feeling a little stuck on the work and activities section. I have been working as a nurse for the past 2 years, but have a long list of jobs and activities I have participated in over the years. The main question I have is whether I should bulk all of my nursing experiences together and title it something like “Various nursing positions”. Or if I should just touch on one or two nursing jobs that have had the most impact on me, and leave the others off so I can focus on other things.
