Our team can add node icon later but so far I feel this would be a good addition to the existing node base. Thank you for proposing this.

Seems Dynamo SelfServe PR check not triggered correctly for this PR. I am running on demand job at https://master-15.jenkins.autodesk.com/view/DYN/job/DYN-DevCI_Self_Service/917/ and monitoring the results. FYI: @DynamoDS/dynamo

I see the following regression result, can you take another look?

Failed : DSCoreNodesTests.StringTests.GetNumber
  Expected string length 12 but was 5. Strings differ at index 2.
  Expected: "01 Level 200"
  But was:  "01200"
