TM1 security in FM package

[rellaize]

Hi,
I'm using several cubes in FM model and publish within one package. Some users have no access to some cubes set in TM1 and when loading the package (or running a report based on) they get an error of TM1-ERR-0054 A CUBE WITH THE SPECIFIED NAME ("CUBE_NAME") CANNOT BE FOUND ON THE TM1 SERVER. I tried to apply object security on the cubes in FM, but it seems cognos validates the source before checking FM settings and the error still appears.
Is there any way to configure cognos to not read all cubes from package when loading or running, keeping TM1 security as is? Or shall I rather create miltiple packages containg one cube?

Thank you,
R.
