UE5.6, Where is the select texture ComboBox of "Required Texture Resolution" Viewmode?

view mode change to : Optimization Viewmodes->Required Texture Resoution"
In UE4~UE5.5 there is a select texture combox.
but UE5.6, I could not find the ComboBox for select texture. Where is it now?

Have you found this yet? I just upgraded and can’t find it either?

I’m looking for this too.
