Add multiple textblocks to same node

I need to add multiple label to my node to denote different section, is it possible as like in below image.

Currently i have achived that thing by adding extra spaces between two text items but it create a lot of issue with respect to alignment.
Below is my code:

  1. $(go.TextBlock,{font: “100pt sans-serif”,textAlign: “center”,overflow: go.TextBlock.OverflowClip,width:
    1200,height: 2100,verticalAlignment: go.Spot.Bottom},new go.Binding(“text”).makeTwoWay());
    2.text:“Bpx1\n\n\n\n\n\n\n\n Box2\n\n\n\n\n\n\n Box3”;
    please help…

Have you read the intro page on panels? You should be able to use some combination of different panels to achieve what you want, with TextBlocks positioned within those panels.
