Expense Settings - Custom Field for Expense reporting

[lsywassink]

We use custom fields to manage a drop down list of account codes for our projects/activities.  When the user creates their expense report, they simply select the appropriate account code for their expenses from that drop down list.  Our drop down list is getting extensive and we would like to inactivate some account codes for projects that are now closed.  The only options I see for managing the list items is to add a new account code, edit an existing one, or delete the account code entirely.  Is there a way to "inactivate" an account to remove it from the drop down listing of account code choices, but keep all the data?  Do we lose all the history of what was coded/charged to an account code if the account code is deleted from the list items?

@lsywassink historical data will not be removed. So, if you delete an item from the list, all reports that have been processed will not be affected. Only reports that are currently created and not been fully processed would be affected.

For some reason it was believed if we deleted from this listing, we would lose history and reporting ability.  Thank you for your help!
