"My Preferences" Option in Instantis EnterpriseTrack

Hi,

In Instantis EnterpriseTrack, We want to hide few of the sub options under "My Preferences". For example: Changing password, Editing the preferences, My delegations and my certifications are the sub options under that. We don't want to display My delegations and my certifications for normal users. But we found that there is not option to hide few of the sub options of "My Preferences". So we have hidden the whole "My Preferences" option using permission. But now the users can't change their password since Changing password option is under "My Preferences". Even the forget the password didn't work for them.
