Backups with data retention plan

Using Acronis True Image 9.5 / Console, I would like to back up a total of 7 windows 2003 servers.  Each server has a "drive B" (for Backup, get it?) which is either a physically connected USB drive, or a mapped drive leading to a USB drive shared on another system.  So far, I can remotely install the Agent and run backups just fine.  However, I have a specific goal for backing up these servers, all of which are part of our small hosting service.  What I would like to see on each server's B drive, after two weeks, is something like this:

server01_full_1
server01_incremental_1_1
server01_incremental_1_2
server01_incremental_1_3
server01_incremental_1_4
server01_incremental_1_5
server01_incremental_1_6
server01_full_2
server01_incremental_2_1
server01_incremental_2_2
server01_incremental_2_3
server01_incremental_2_4
server01_incremental_2_5
server01_incremental_2_6

Now, I don't really care what file names I end up with, but you get the idea -- the above represents two full weeks of backups with data retention, with each backup going into a separate file each evening so that if a single file becomes corrupted, it only affects that file.  At the start of the next week (i.e. after incremental_2_6), I'd like Acronis to remove all of the files from the very first week, but I don't think it can do that... I'll probably have to write a script for that.

After banging around with this software for a while, i get that you can create a full backup file, for example "server01", and then schedule nightly backups "based upon" that file, which Acronis will automatically name something like server011, server012, etc.  What I don't know how to do is get it to start over with a new full backup file the following week, and base the new incrementals off of that.  

I may be "to into" the way I'm used to doing this with NTBackup, so I would like to know... can someone give me a step by step instruction set for accomplishing this goal?
