Remove Unused Paragraphs Styles (Feature request) #216

I wonder if is possible to implement a feature to remove unused paragraphs styles as it is already in the colors palette ?
The reason of this idea is to simplify the burden when importing formatted text and try to assign new styles
I currently struggle a lot with text that has bold or underlined words.and I end up having many different style sin the styles palette but I have to remove then manually -one by one-
Not sure if this feature could ease the process at least.. or either been able to select multiple styles and press delete so they all go away .. (hope it makes sense)
Many Thanks..
