ANSYS workbench simulation join

[ayahk]

I am new to workbench and i just need to know if its possible to join 2 simulations in 2 different files to one simulation in a new file.. and if its not possible then how can i transfer the result of for example (Static structural simulation to another static structural simulation) in the same project.. i tried but its not allowing me to join or transfer results.
I also need to subtract the result of both simulation from each other to get a graphical representation of the error is this possible? or there is no such thing?

Thanks alot!
