Is it possible to split panels on Dashboard into 3rds?

[DATT]

Dashboard studio gives me the ability to drop panels and and move them around, which I love.  I can drag a panel on top of another and quickly create two equal size panels, each 50% of the size of the dashboard.  If I drag a 3rd panel into the same area though, I get three panels, one of which is 50% of the screen, and the other two are 25% each.  Is it possible to get them to be three equal sizes (~33%) or is my only option to fiddle with the sliders a bit and settle for good enough?

If you edit the source of the dashboard you should be able to find a section called "layout" within the JSON, as below. 
Adjust the "w" value for each of your visualization to 1/3 of the "width" value (in my case 1440/3 = 480).
Set the second viz "x" position to 480 and the third viz "x" position to 2x480 (960) and this should give you an even 1/3 split.

It doesnt look like there is an easier way (ie it "snapping" to 1/3 grid size) unfortunately.

"layout": {
        "type": "grid",
        "options": {
            "width": 1440,
            "height": 960,
            "display": "auto"
        },
        "structure": [
            {
                "item": "viz_NFlIOSoJ",
                "type": "block",
                "position": {
                    "x": 0,
                    "y": 0,
                    "w": 480,
                    "h": 250
                }
            },
            {
                "item": "viz_ZN3u7AG0",
                "type": "block",
                "position": {
                    "x": 480,
                    "y": 0,
                    "w": 480,
                    "h": 250
                }
            },
            {
                "item": "viz_6G8sJ2GL",
                "type": "block",
                "position": {
                    "x": 960,
                    "y": 0,
                    "w": 480,
                    "h": 250
                }
            }
        ],
        "globalInputs": [
            "input_global_trp"
        ]
    },

  I hope this helps!

This worked for me on a fresh dashboard, thank you.  

I tried this on an existing dashboard though and quickly found out that if you get the numbers even off a little, you end up hiding/deleting (I wasn't sure what actually happened) other panels elsewhere on the dashboard - It's like they get pushed off into the ether.  I ended up having to rebuild the dashboard from scratch 😞

A friendly heads-up for anyone that comes along in the future!
