Hiding dimension from pop up label mekko chart

[#1]

Hello,

I have a mekko chart with two dimensions.

The first dimension is a drill down group, consisting of: Channel > Trade Type > National Customer

My second dimension is National Customer

The purpose of having the second dimension is to show the customer break down when the mekko is at its highest level - Channel.

The problem is that the pop up label lists Customer details twice when the chart is drilled down to the lowest level.

Is there a way to hide the solo Customer dimension from the pop up label?

Thank you,

Mel
