Icons Conditional Formatting on Hierarchy

Hello Power BI Community,

Love the ability to use Icons when conditional formatting a column in a matrix. Though I have hit an issue that I'm hoping there is an answer or at least a work around. I only want to show the icon ( up or down arrow), not the value, which I can do through the conditional format icon window. 

The issue I have is when you then drill down into a hierarchy (rows) the icons remain for the newly opened child of the parent group but the parent member doesn't have an icon and shows the data value (see picture below, parent row highlighted in red). I've tried changing the colour of the font but I have alternative row colour therefore that wont work and at the same time I need a Total row at the bottom yet the Status column colour should remain blank, which is does. I'm linked straight into an SSAS therefore functionality is limited.
