If all your Selected users are from the same IP subnet you can use multiple Virtual Serve with the 

Source address
set to the Select users subnet on the first one, then assign different pools based on where you want the users traffic to be directed to.

E.g.

  • VS1 Source Address=< user subnet > Pool=< Select Server pool >
  • VS2 Source Address = *(any) Pool=< Other Server Pool >

See the following for the selection order of Virtual Server on LTM: K14800: Order of precedence for virtual server matching
