GL - Investigate Possible Customization For Expense Sourced Journals

Can you please check if there is a possibility to change the current set-up/source for column "journal line description" on journals having EX as source.  We currently have the employee ID as a source, our need would be to have the description mentioned in the expense.

1. Create expense report

The description is filled-in.

1. The expense report is being reviewed, approved and transferred to GL via EX-GL batches.
2. Currently journals (EX source) have the employee ID of the person who created the expense on column “journal line description”. Our need would be to replace the employee ID with the description of the expense, mentioned above. Column/field “reference” is useful the way it is right now, because it leads us to the EX document.
