BU name required as source in Manage Description Rule

Summary: Option to have Business Unit name as Source in Manage Description Rule

Content (required): We are trying to create a description rule for payables in Manage Description Rule. Basically we need Business Unit name as our description. Only option we see as 'Source' in Manage description rule is "Invoice Organization Identifier" through which we are getting Business Unit ID but not the name as description. Is there a way we can have BU name as description? We need to have this Business Unit name appear as description under Subledger Journal Lines.
