Force PHP settings in Packages

Hi,

quick question.

Any possibility to hardset some php settings inside packages for the users?

Like:
Package S = 8mb filesize, 64mb ram ussage, 180seconds runtime  ... (php settings)
Package M = 64mb , 128mb ram  --- ...
for exmaple in plesk, i can set some hard limits, like max uploadsize, runtime and more. - the user cant edit the settings after if not enabled to edit in package.

i just have found "global" options or edit all users manually and disable the edit php.ini in the userinterface..but that is .. urgh .. ^^

sry for my bad english, not my native language
