Best Way to Average Array Rows with Same Value in First Column

[Testy]

An example of what I'm doing:

 

Given:

[1,2,3;

2,2,2;

2,4,4;

3,1,1;

3,3,3]

 

Output:

[1,2,3;

2,3,3;

3,2,2]

 

So that the output array has unique values in the first column, the values in the other columns being the average of the rows with the same value in the first column.

 

The code I have right now is this:

 

Is there a simpler way to do this?

It doesn't look like your attached any code.  Yesterday there was some LAVA issues so this maybe this is to blame.  In either case I've attached my go at it.  This uses two OpenG VIs Remove Duplicates and Search Array.  Install the OpenG Array package to get these VIs.
