Cascading IFWRotate Backups

[RCFitzhugh52673]

I have several machines running IFWRotate backing up to a server. I have excellent backup success when they are run sequentially. I currently have this setup through task scheduler. What I am looking for is the position in the IFWRotate script that can call the next IFWRotate task in series once the first IFWRotate completes with or without an error. Anyone have that and any command sequence needed? Thanks
