TC File Sharing "With accounts" ability to choose hard drive?

CLARIFICATION:

Hi!

I've TC 1 TB, latest model (Early 2009 in Apple terms I suppose).

Can I have private folders in EXTERNAL USB drive for accounts?

I've created two user accounts via Airport Utility->Disks->Secure Shared Disks: With accounts.

User account 1 sees three kind of Sharepoints via Time Capsule's entry under Shared-category in Finder:
- external USB drive in whole (bad bad)
- entry for main level so internal disk inside TC
- dedicated account directory for this user account (let's say: account1) in TC's internal drive

User account 2 sees:
- external USB drive in whole (bad bad)
- entry for main level so internal disk inside TC
- dedicated account directory for this user account (let's say: account2) in TC's internal drive

If wanted scenario isn't possible in TC, how about Airport Extreme, can disks be controlled there separately?

Summa summarum: I'm trying to have poor man's fileserver in my home network. Target is to have common place for users' files (while maintaining privacy), so external USB drive for this purpose. TC's internal drive dedicated for Time Machine backups only.
