Multiple company associations at Success Plan level.

Use case : We are onboarding our Partner implementation team onto Gainsight and as part of that, they will be using success plans. Partners may be have multiple implementations for different customers. To manage this, we are creating success plans for every customer under the partner and linking them to accounts using a lookup. 

Suppose if a partner manager is logging an activity on Success Plan timeline, they would want the same entry to be recorded against the Partner account and Customer account in 2 different timelines so that partner manager and customer success manager are fully aware of what is happening with the implementation.
