I have a table in Zoho Analytics that I manually add records to:

UserName - StartDate - EndDate

ExampleData:

JoeSmith - 1/1/20 - 6/1/20

JoeSmith  - 6/1/20 - 1/2/22

JoeSmith - 7/1/20 - 1/2/22

Is there a way to prevent the last entry from being entered/saved as it overlaps the time noted in the second entry?
