increasing waiting time for duplication

Hello,

is there any possibility to increasing the waiting time for duplications? The Problem is, that a lot of Backup Jobs start at the same time. The duplicate should start after the backup has finished. But sometimes the library is reserved by another duplications. So the duplicate Job has to wait more than 24 hours and get into the status missed. Is there any possibility to increase this timeout?

Thank you very much in advance,

Daniel
