Loco Setup Bringing Custom Livery From Tsw Livery Designer To My Custom Timetable

Good afternoon, and happy new year everyone!

I've made a timetable for the Riviera Line set when GWR still had 153s. I've made some liveries for the 153 using the TSW Livery Designer, I was wondering if it was possible to transfer them over to the editor to be used in my timetable? Thank you!
