Renaming/deleting assigned ESata drive names

I've been using esata attached drives to backup my RN626X.  My question/problem is each new disk is assigned the name ESATA_HDD_X.  The X increments with each new drive.   The problem is when I created the backup jobs, they "hardcode" this name, so when I try to run the backup job it must be the drive with that name.  I wanted to change the backup job to use a larger esata disk, but I can't edit the backup job's destination.   Is there any workarounds or ways to rename the drive?
