Replace certain items in branches with other items

Hey all,

I have a problem related to replacing certain items in branches.

I want to replace any items less than 1 in in flexible number of branches.

My data structured in this way for example:

Branch 1

0 --> need to replace this with other number

2

5

7

Branch 2

3

6

8

0  --> need to replace this with other number

I know a component Cull Pattern that removes the items. But what I want is to replace those items with other item, lets say replace any number less than 1 with the number 180. 

Please suggestion, thanks in advance.
