Currently is not possible and you need to do it manually each single time. We can use the icon to display bitmap in display or enable the “realistic/standard materials in display” option. But this only affects the current materials and for any new bitmap we need to repeat the same operation.
We need to be able to toggle the option where any new bitmap will be displayed automatically.
Currently is a waste of time for a process that should be transparent for the user. I remember countless times pressing that "show shaded material in display" that also is confusing as it quite similar to "show background in preview". Lets get rid of unnecessary steps.
