Possibility for a Task to be associated with multiple Campaigns

For organization and planning purposes, multiple teams create their own plans and views, often with multiple tasks being created and living under different campaigns, but for the same Marketing objective, for example, a new product Launch.

The possibility to be able to have a Task associated with multiple campaigns would enable visibility for the different users plans (saved or not) when filtering, while maintaining their original preferred setup.

For example, I may have a Tasks in Campaign A that is for a Marketo e-mail, but I want this same Task to appear listed under "Activities" tab on Campaign B (if I so chose to do so, not by default, it needs to be an explicit user action).
