task layouts on a task list basis (instead of per project)

task layouts are amazing. the ability to add custom fields, and have them available on iOS, and also have the ability to bulk change the custom fields is great.

our issue is that we need to have different task layouts for different types of task lists.
it would be great if we could adjust the task layout on the fly on a per task list basis.

this would tremendously help our work flows.
current if we do it project wide, then having a default value hurts us instead of helps us.
we would only want a default value for specific task lists so that in the future when we need to find and filter tasks the default values would help us.
