How can you populate active and inactive users in Assigned To field?

Hi,

I am using SugarCRM Professional 7.2

Module: Meetings

How to populate inactive users in Assigned To field?

By default only active users are appearing.
The logic is when we create a new user then that user becomes also a employee and when inactive that user then that user not able to login but that user still showing as a employee.

Here I need to assign the record to a employee who is not a user means when I will go for select then both active and inactive users show please help

Regards
