Is there a way for you to put delay in between the duplicated action coming from the slave character?

Say i am duel boxing 2 mages, i cast frostbolt on my host character, and then 2-3 seconds later then it's my slave turn to repeat that attack. The problem is im new with this so i have absolutely no idea how this could be done, i can duplicate actions done, i just can't make it so that there are some delays inbetween them.

I want to incorporate the delay on all of my comands, including my movement, everything, is this possible? Any help will be appreciated, ty.
