Uni-Int to write to scan-class health tags on startup

We've noticed this particularly with the RDBMS-PI interface when configured for failover: Health tags that are only written to when the interface becomes primary or has completed its first scan (eg Point Count, Scan Class I/O Rate etc.) say 'Intf Shut' when the instance is actually in 'Backup' mode. Even when changing to Primary status, many of these tags don't get a value till after the first scan, which could be quite a long wait. I would like UnitInt interfaces, on startup, to post an 'Initialising' or 'Awaiting 1st Scan' or some such digital state to all health tags that would otherwise still be saying 'Intf Shut'.
