Yes, while creating the asset type, there itself you can opt for Lease type (YES/NO)
For YES, it asks for entering the lease amount for that asset and also asks for the Lease amount under tax exemption(YES/NO)
Path : Admin Settings >>Asset Settings >> Asset >> Add New >> Lease type(opt as YES) >> Enter Lease amount >> Choose tax exemption >> Update
Here, the existing asset type with no lease is also converted into a lease asset with asset type EDIT.
