Yes my feature request is related to a problem

A clear and concise description of what the problem is.
Im using balloon compose but when i try to use the BalloonOverlayRoundRect it takes only parameters for x and y so its impossible to set the corner radius of the overlay to only one side of the BalloonOverlayRoundRect for example if your anchor view is at the edge of the screen and unpadded then the overlay will just pass through the anchor.

Describe the solution you'd like:
is it possible to implement something like this RoundedCornerShape(topStart = 14.dp, bottomStart = 14.dp) from compose. shape?

A clear and concise description of what you want to happen.
I want to be able to set the corner radius on only one side of the overlay so that it doesn't pass through my anchor view content
