With NLB, no, however administrators can target individual servers by using mstsc /admin. If you have a hardware load balancer, regular users most likely can target individual servers (depends on how the VIP is setup).
That said, targeting individual servers is usually a flawed design. I would avoid this, as it usually means there is not proper redundancy for an app, or the load may not be properly distributed.

This should only be reserved for admins as you want your regular users going through the farm with a broker and DNS round robin setup.
To do this as an admin click Start > Type MSTSC /admin > Hit Enter
Alternatively you can click Start+R > Type MSTSC /admin > Hit Enter
And finally, you can open Remote Desktop Connection and type he computer name you want followed by /admin to login to the specified server.

Yes, I believe this can be done via a TS Session Broker Load Balancing.
