EMR Class 180s - Set Routes / Times?

[Inthewest]

Are the EMR Class 180s allocated to specific diagrams every day?
If so, does anyone know what these may be?
Don't fancy waiting around for one to turn up.

There are set diagrams for the 180s which are listed here: https://railforums.co.uk/threads/emr-diagrams.212284/

Weekends may be different due to engineering works and the strike action.
