Scope inbox availability of tags when importing channels

When an Outlook/gmail inbox is setup as a channel to a Front inbox, and the option to create tags based on Outlook folders/Gmail labels is enabled, the tags show up for all inboxes by default. However, for some customers, this is not the desired behaviour, as they want the tags to be scoped to certain inboxes only.

Could we enable admins to define inbox availability when tags are created in this way? This could also be paired with a 'Tag bulk update' feature, in case tags were mistakenly imported with the wrong inbox availability.
