Yes. 
2 parameters, one for the toggle in your menu and one for the randomiser.
Make an empty state as the default state which will have nothing on it and a second empty state which will have the parameter driver on it which is what your toggle will be for in the menu. Make sure it's set as "local only" so that it syncs the same value with everyone. I know it doesn't sound like it will by that naming they use there but it does believe me.
You'll then transition from the second empty state to the 2 animations that you want to randomise between by using the second parameter that's being driven by the second empty state.
This probably doesn't make sense because I'm bad at explaining things and sleep deprived. I'm going to bed now so I won't answer any questions until the morn, good night~
