Report - y axis names with 'n systems' plots

Hi,

Using NSystemsMode set at e2DAxisNSystems I can create a plot in Report like below.  However, I am not able to change the y axis titles in a good way.  It appears that all plots take the same name (example: 'Plot name' in the picture) .  I would like that each plot has the y channel name of the curve as the axis title.  How can do this using script? I have not found a way to access each axis separately...

Any help is appreciated.

Thanks

Thomas
