Software delivery cache folder location

We currently have Windows 7 64bit OS with two partitions. (C and D) They are running Symantec Management Agent v7.5.

The question I'd like to ask is, is there any way to make the download of packages to go to the partition with most free disk space automatically?

For example, if C-drive has 40GB free space and D-drive has 500GB free space, then the download of package automatically goes to "D:\Program Files\Altiris\Altiris Agent\Agents\SoftwareManagement\Software Delivery\"

Many thanks in advance.
