Custom Sync Filter Using Multiple Fields?

Hello Everyone,

We're trying to prevent specified new leads in SFDC from syncing to Marketo until they are converted into active accounts. I understand you can create a custom sync filter to do this, but was wondering:

1. Can this be done combining logic from 2 different fields? Ex:
   1. If unregistered_lead_c = True AND Account Status = Not Active, do not sync with Marketo
   2. If unregistered_lead_c = True AND Account Status = Active, sync with Marketo
2. Can the logic to sync/not sync be based off of a specified status, or does it have to be a boolean field?
