Activity Overlay

Hello Everyone, I have a MK1 descent (previously used a Fenix 5 hr) and I am trying to figure out if there is a way to see all hiking activities on one map (like an overlay). Essentially I want to see all of the trails/ground covered in one area. Does anyone know how/if this is possible? I use the connect app and am very familiar with how to see each individual hiking activity on the map but can i see all(or some) at once?Thanks!
