As a Product Owner I want to split an epic easily

so that I can save time in grooming and I can see all information for what I am splitting.

Example Scenarios:

• I created an epic that is too large. I want to split it into 2 and re-define requirements across two epics.
• In grooming, one story is estimated too large. I want to split it into two stories

Current Solution:
Cloning - However, I lose track when using two tabs. I would do it away from the team and they have to wait on a future grooming to re-estimate.
