Within the Salesforce integration config, allow the ability to access the "Company Annual Revenue" value on the Lead Integration Settings instead of strictly providing this field value on the Account Integration Settings.
Make this field available similar to "Company Employee Size", which can sync into Salesforce Leads records.
Companies importing Leads directly may need this information as part of routing logic for Market Segments and need that information on the Lead side of the funnel rather than strictly being available on the Account.
