When applying a global roughness change in ISIS it only applies this to river sections.

Given that the bed under a bridge is nearly always composed of the same material as the bed u/s and d/s of the structure, could the global change be altered to allow manipulation of Manning's under the structure?

...on the global roughness form there is a new check box to select whether to apply to bridges

A nice additional tick-box to include structures, or not, would seem good to me.

This has been added (ISIS 3.5.1)

Whilst looking at this, it would be good to stop ISIS writing at the beginning of a run the warning about changing N in a section that appears in the zzd diagnostics for bridge sections as this distracts from identifying where this warning is actually important
