"left to right direction" in Work Breakdown Structure (WBS)?

Question

Would it be possible to have support for left to right direction in Work Breakdown Structure (WBS) diagrams?

Basically if I have this:

@startwbs * Business Process Modelling WBS ** Launch the project *** Complete Stakeholder Research *** Initial Implementation Plan ** Design phase *** Model of AsIs Processes Completed **** Model of AsIs Processes Completed1 **** Model of AsIs Processes Completed2 *** Measure AsIs performance metrics *** Identify Quick Wins ** Complete innovate phase @endwbs

Add "left to right direction" to get somthing like this:
