How do I automate the Proceed? YES answer when restoring using ./pleskrestore?

[bppilot]

When running ./pleskrestore, I'm shown a warning message that asks the following question:

WARNING! Restore with "-level server" switch brings server to exactly the same
state, as was saved in backup file. All objects, not presented in the backup
file (clients or domains) will be deleted. Proceed? [yes/no]:

Is there some command line switch that will all this to automatically proceed without the need to manually type in YES each time?

I'm wanting to do this as I've got an automated backup and restore routine that I'd like the server to run without user intervention.

Thanks for any suggestions!
