Banner Blankets?

(Bedrock) I figured since banners are so customizable, why not give blankets that same customizable power as well? Perhaps crouching with a banner in hand and interacting with a bed could allow you to change the blanket design from a solid color to a design you created. The color of the bed could still be viewed by making it so that the banner design only shows on the top of the blanket and not the entire thing, and the sides would stay the same color as it normally was. I think it's a really small change, but it would be fun to be able to customize our literal spawn point of choice to our liking. [This could also be very helpful in Java as you can use banners to mark points on a map, so you would be able to mark your spawn point perfectly by using a banner blanket]
