How To Run Custom Formations In Custom Scenarios/timetables?

Was wondering if it’s possible to run custom formations in either scenarios or timetable runs in Train Sim World 4? If so, how do I do this?

 

I know you can spawn in custom consists whether in free roam or timetable mode. Make sure to set the destination so you aren't stuck at a red

 

Ok cool. How do I spawn the custom consists though? I havent found anything that lets you do that

 

When spawning in a train through the TAB menu, there will be three headings, Official, Liveries and Custom formation, hope this helps!

 

Thanks!
