Is it possible to stop a shuffle loop value and store it in an array.

I would like to know if it is possible to stop a shuffle loop value and store it in an array.
I have another BP in which new characters are shuffled every 2 seconds. This BP should shuffle the characters without repeating . If I could manage to stop a shuffle value, I could apply the 10 random numbers to my characters one after the other. May this question is unusual, but I am a Unreal beginner;)
