Particle Emitter start and end times to be visible in dope sheet

At least I've not found a way to do this but it would be cool to have a visual representation of Particle emitter "Frame start and End" times visible in Dope sheet (timeline, graph, etc.) so that when you need to change more than one Particle system in time it would be easier to do.

For example I'm working on a VFX shot with multiple objects that have their own unique particle system (over 40), emulating a gun shot hit spark and now the client has extended the shot which means I would need to offset all the start and end times for every particle system one by one. So, something that would make offsetting these settings easier would be awesome to have.
