Ability to make timeline entries on the relationship level also available to customer level

Some business cases for relationships change and we are moving away from a Relationship in GS but we want to retain the timeline entries as it still pertains to the account. It would be really great to have an option to either move/copy or make available the relationship level entries within the customer level timeline. For now I have created a report to display on the C360 for all entries but that is redundant and does not look as good as the timeline feature.
