Exactly, It's too messy to do it that way, and hence I had to post it here to find an alternative for it.
We also need a decoupled solution. We thought of pub-sub but have no idea on how to implement it (Cant find much about this topic). So if anyone knows of such a way to do it , this would help a lot. This is one of our common requirement, cause we have many zones under multiple nested components in layout component and on action of some of the nested components in pages, those layout component needs to be updated.
