Section Progress Bar - Use Dynamic Colour to hide element

I have a few elements on a canvas that I use a project script with shared variables to update text and background colours of a few labels.

I also use this shared variable to set a section progress bar colour dynamically.

When I send an empty string to a label, the background becomes transparent (aka hidden) but a section progress bar stays visible and goes back to default green.

Would be awesome if section progress bar could go transparent (aka hidden) when you send an empty string into the dynamic colour field. Currently using a script and listening to sockets to update CSS when needed, but the colour settings would really simplify things :slightly_smiling_face:
