"Global" Success Plans shared across multiple accounts

We have global customers that have separate accounts owned/managed by different CSMs in different regions, but they still need to cross-collaborate when it comes to larger, organizational goals and objectives.  Today, they have to maintain their separate SPs in separate accounts which makes collaboration and cross-regional visibility difficult.

Need the ability to have “global” success plans that can span more than one account, accessible and editable directly from each account.  This is a pretty common use case, as I’ve encountered it at previous companies as well.
