Retrieving line level set with Volume indicator

 
In the Volume Indicator with MT4, in the properties you can set "levels" which would draw visual lines on the volume chart at a specific volume quantity. Is there any way you can retrieve on an EA the volume quantity at which these 'level' lines are set at the present time, when you possibly move these level lines around manually?
