Changing Format of text within multiple selection block

One of the pages we use we list 4 options of medications, we want to make part of the option text in a different color as we reflect availability of products (either available / not available) and we want to show available in Green and not Available in Red, I have tried to change the text color but I’m not able to adjust part of the text (I’m only able to change the text color for all options).

Please check the screenshot below for more clarification, I would really appreciate it if your team can help us do that or guide us with a workaround. (The part of text that we want to change text color is red-squared)

We don’t support multi text styles on our button group field as of the moment. Best way to do this would be to set them up as separate buttons (which do support multi-styles) and have the click action set the value of a field
