Export tracks to other project

I have a motu interface with 24 analog in and 24 out
All the recorded music goes to the ouput 1-2
the new tracks that I want to add and copy the routing to other songs are:
Piano HI, use Neve 1, is the analog input 1, then goes to the analog output 3-4
Piano Low, use Neve 2, is the analog input 2, then goes to the analog output 3-4
Piano Bottom, use Capi 1, is the analog input 3, then goes to the analog output 3-4
Piano Room, use Capi 2, is the analog input 4, then goes to the analog output 3-4
