Is it possible to recover a portion of a save set by pointing it at a specific tape or telling it not to recover anything from a specific required volume?

For example, if you need to recover a full save set that spans say 5 tapes, and tape 4 of 5 is a problem tape, you could obviously start the recover, and then when it gets to tape 4 you could then cancel or simply not even have that tape loaded to begin with in which case NetWorker will ask for it, and then you could cancel the recover. Obviously, you wouldn't end up with everything, but you'd at least have the first 3 tapes, and that *might* be better than nothing. I don't see any way to do this in the GUI, but is there a command line work around wherein you could do a save set recover against each good tape by somehow specifying the file or starting record number? I know save set recover will not remove data like a browsable recover will so you might end up with extra files, but that doesn't seem likely in a full restore, only if one or more incrementals were also specified, and even still that might be better than nothing in certain circumstances.

Just seems like with save set recover that NetWorker outa be able to work around one or more required tapes and just pull off whatever is there, leaving it up to you to deal with the aftermath. If NetWorker knows where the save set starts on the tape then why should it matter whether or not it has one or more of the required tapes, except for the one actual file that spans? Maybe not that simple?

Just curious.
