FDE in MODE can simulate mode properties such as mode loss.

You will be able to get the loss for each individual modes. How do you calculate the "combined" loss for a few modes together will up to you. 

Whether the mode is physical or not, you can use PML and set sufficient number of trial modes, and see if the mode appears.
