Is there a way to do this in labview

[Canucks.canucks]

This is my vi. If you enter values like 7,3,1,4 it calculates

7-3=4

3-1=2

1-4= -3

now is there a way to do the following?

I enter initial value lets say 2 and vi do this ( basically appends to array and deducts first element from it)

2-7=-5

7-3=4

3-1=2

1-4= -3

Yes, you initialize the shift register by wiring into the left side of it.
