SRichTextBlock Opacity

I was hoping to replace the STextBlock in ShooterGame’s chatWidget with an SRichTextBlock to provide for different colors on the line (player name green and their message white for example), I’m finding though that SRichTextBlock does not have a .ColorAndOpacity member that I can use to fade the text out. I’ve looked at the source for STextBlock and SRichTextBlock and it does not look like it would be a trivial amount of work to add this, am I right in assuming this?

Is there another widget or approach I can take to achieve richtext and opacity?

I’m in the same boat with 4.8. It’d be great if SRichTextBlock’s TextStyle could be set to a delegate instead of a fixed value.
