System validation if performance goal name is not unique

Summary:

Hi Team,

We have a business requirement where they want to restrict an employee from submitting goal name which is already present in his/her current goal plan.

E.g- an employee has already added one goal as 'productivity' in the Goal Plan - "Performance Year 2026-27" then he/she shouldn't be able to add another goal with the same goal name

Do we have any validation which can be created through VBCS?
