When configuring a drill-down pop up window, a developer can pre-configure an entirely different layout with a filter applied from the drilled-into row.
In our case, we have configured a pop-up to enter comments, saving space within the data entry view. However, when we drill into a member with a Row Template applied, there is no way to remove the row formatting. In this case, the % should not be displayed as it is not relevant to the text comment inputs for this combination.
