Thank you for your great idea. While we cannot commit to a specific target version, we will consider adding it to our future internal backlog. If you can add further information about the context of this feature, please add it here so we can evaluate it more fully.
As a more individual setting, users can always enable a "hold" for a specific cube coordinate to exclude it from splashing. However, we understand, that the ask is more related to a general setting on dimension level.
