# Font Size changing automatically in textbox in slide master

Hello you wonderful group of people :)

I am having a major headache with the following setting: I have a bullet list, and the first bullet requires on font size and the sub-bullet point requires another font size - the bullet list is in a textbox, which is in the slide master of my current employer - therefore I have visual identity brand guidelines which I need to follow.  When I try to change the font size, all the text (from major bullet and sub-bullet) in the text box changes, and I don't want that. Is there a workaround for this?

Thank you,
