show bitmaps after converting standard materials

it seems as if i have to manually go in and turn on all show maps in viewport for all the materials after converting a scene, is there a way around this?

Views > Show Materials in Viewport As > Shaded/Realistic Materials with Maps .
But it is a global switch and if you are using any special maps like falloff,VrayDirt ..etc then you need to fix them manually.

aha, only used that in some cases, very helpful, thanks @M.Max
