I am trying to find and replace an arrangement of 6 letters\special character\numbers.  

For example they appear as such in my original code 

```
DEVICE_NAME","CB2_02 DEVICE, DEVICE_NAME","CB3_09 DEVICE, DEVICE_NAME","OB6_12 DEVICE...

```

The order in which the letters, numbers, and special character appear are always the same. I need to replace the `_` (underscore) between `CB3_09` with a `-` (hyphen).

I can easily find what I need using:

```
DEVICE_NAME","(.*_.*) (device)

```

but am having issues replacing the `_` with a `-`.
