Evening all, hope you are all well.
I'm trying to configure sorting of a view we have in Dynamics but the option/column doesn't seem to be showing.
The column in question is a related account field that I added but it fails to show -
Column on the right:

Options available:

Is this something that I'm doing wrong or is it not supported?
If it's not supported is there another way to add this in?
Thanks in advance!
Sam
