Can Plug-in for SQl Server warnings on system databases during incremental backups be skipped? (4042963)

Because MS SQL Server system databases (master, tempdb...) are always in Simple Mode, when incremental or differential SQL Server backups are run, NetVault will return a warning that incremental method on databases in simple mode is not possible.

While these warnings are obvious, they set the job exit status with warning even when all databases have been successfully backed up, prompting users to verify whether each job has completed fine or not.

Is it possible to filter these warnings so the actual backup task completes successfully?
