Mixin fields with tabs

Need Help
#1

I have a mixin, who’s fields I’d like to show on a different tab depending on where it’s used.

handle: Section\Title
name: Title
type: mixin

fields:
    title:
        tab: Content
        label: Title

And then I go to use this mixin in another blueprint like this…

handle: Content\Settings
type: global
name: Settings

fields:
  _title
    type: mixin
    source: Section\Title

Is there a way to get the fields from the Section\Title mixin to display on a different tab ?

In this example I’ve tried setting a tab: value when using the blueprint (see below) but the fields still show up on the Content tab.

_title
  tab: Title
  type: mixin
  source: Section\Title
