I'm working on integration from SF to Odessa LeaseWave. We have some Picklists that aren't matching up perfectly so I have created some "translator fields" so we can translate our picklists items to fit with picklist items. We've found another one where we have discrepancies. We don't want to change our fields because we count on that data and they don't want to change theirs either. 
I'm wondering if there is another way / a better way of doing this?
