Allow column type to change without worrying about view dependencies

Good morning,

When there are lots of views and complicated dependencies, it is not 
easy to alter column from varchar(a) to varchar(b).

Is it possible when defining a view, adding cascade or some other key 
word(s) to allow column type change?

When column1 is changed, all related views' column type is changed as well.

Thanks,
