When does array due to?
If they are symmetrical you could do 1/4 or 1/2 of them and simply mirror the remaining.
Or you could do successive copies; 1 to 2; 2 to 4, etc.

We are working on the 3.7 version, that contains more sketching improvements. Array is currently under planning by the product team
