This will not work at all. Routes are dictated by ip adddresses or by traffic-type , not by user groups or user names. ISA does not have a way of assigning a route to a user group name. Bottom line, ISA would not know which external interface to use so would use the default one all the time regardless of the internal user involved. Sorry.

It does not work very well, I would actually buy an appliance to solve this like a watchguard or a F5 balancer.

thanks all

thank you Mr. LABCIS

Mr. keith_alabaster are there any solution like what Mr.LABCIS said ?

Not based on the requirement you have listed because you are basing the need on a username and usernames cannot affect the network layer.

A work around could be as simple as placing the 2nd Internet connection directly to a network card on the PC used by the manager with a personal firewall installed so that it is for his workstation use only. This would remove the need for him/her ti use the ISA server for filtering.
