Thanks Shruti for understanding the exact scenario 
At present there's no ABAP indulgence.Also trying to avoid the same if it's possible by standard
In ESS I've no issues if I am creating another Leave type PL(FTC) using WEBMO Feature.
Only in backend it'll appear 2 times as PL and PL (FTC).
End-Users afraid of audit / compliance issue as they might be caught treating FTC separately from Regular staff . It's silly but realistic business scenario
