Defining a new SideSet in Exodus file


I have a .e file that contains the results of my simulation. I need to use that .e file to run another simulation, but this new simulation needs a new sideset (different from the sidesets defined in the first mesh).

Is there any way I could add a new side set in my exodus file using ParaView?
I need the exodus file that contains all the original mesh, the simulation results, and the new side set.
