Adding " No" in the drop down for the Plug Account and IS ICP Entity/Account Property

When new entity or account is created, the initiation is being handled by the finance users. The drop down value we are having is either blank or yes. ideally, we need to give either yes or no.

They couldn't get this logic why blank and yes is there and requesting to add no in the drop down. If we add no in the drop down, it won't be accepted in the EPM application. Kindly suggest a way to manage this.

Kind Regards,
