Spool change of wire

         I am using Creo Parametric 2.0. My Harness Part has 30 wires and 3 spools.Let us consider

a)  10 wires belong to spool A

b)   and next 10 Belongs to Spool B

c)   and the third 10 belongs to Spool C.

      by mistake while routing i did not change the spool name and routed all the 30 wire with Spool A. Now if i want to change the spools as per my requirement what is the solution?

         I tried to go for reroute it will not help.

         I tried route spool is showing but non editable please give me solution.
