Leave Allocation for Overlapping Duration

Currently, Leave Allocation follows the below system:

Suppose I allocate leave type “Comp Off” to an employee for the period of 1st April to 15th May since I wish to have this leave type expire in 45 days.

Now again, I wish to allocate some leaves starting from 5th Apil for the next 45 days duration; it is not allowed due to allocation overlapping.

In Conclusion, I didn’t find a solution to have multiple “Comp Off” leaves expiring on different dates.

Kindly help.
