Allow saving ALSIC posting preferences before all fields are set

Currently when you enter credentials to connect Sage CM to SIC, you're taken to Posting Preference where there are a gazillion fields to populate before you can save the connection. If you time out, you have to start all over with Posting Preferences. Please allow us to sage Posting Preferences before all missing fields are configured so we don't lose that work. Provide a mechanism for not allowing any records to synch until all required fields are entered.
