NBU 7.6 - Do partial restore (have 16/17 tapes)

Hi there

Server is 2008 R2

I have a year end backup that consists of 17 tapes spread across, now I have found 16/17 and want to continue on with the restore, and want to know, how can I force the job to continue and restore what is possible without failing because of one tape being missing.

OS is Server 2008 R2 Standard

NBU - 7.6.0.2
