accelerator forced rescan schedule issues

Hi all,

using nbu 5230 as master server, version 2.6.0.1

All my policies using now are VMware and MS-windows. All with accelerator enabled.

All policies perform a daily incremental backup at Mon-Fri, and a Full backup at Saturday.

I read the guide recently that Symantec suggest to have a schedule with full backup and accelerator forced rescan every 6 months.

My question is, if I also have a full backup (with forced rescan) that runs every 6 months, at the day that this policy run, will I have 2 full backup at the same time? (as I also have a weekly full backup without forced rescan option) 

I want it works like when the policy with forced rescan runs, it will not run the weekly full rescan. Is it possible?

Thanks a lot!
