Timing Diagram - Plot multiple signals onto 1 Y-axis

Question

Hi, hopefully I have not missed this feature in the reference guide. I have found the timing diagram great to use, but I was wondering if it would be possible to have multiple signals share the same Y-axis? 

For example, plotting 'analog' and 'analog2' onto the same plot:

@startuml

<style>

timingDiagram {

  .red {

    LineColor red

     LineThickness 5

     LineStyle 5-8

  }

  .blue {

    LineColor blue

    LineThickness 5

  }

}

</style>

analog  "Analog"  as A <<red>>

analog "Analog2" as A2 <<blue>>

@0

A is 0

A2 is 3

@100

A is 3

A2 is 0

@300

A is 1

Thanks for your help.
