Does P12 have FBX import option to browse to texture folder if hard-pathed location not found ?

I'm running PP_11.3, but intend to upgrade to 12 at its next patch.

At present, I'm wrangling a bunch of budget FBX tree models whose texture calls are hard-pathed deep, deep into eg D: drive. I've no objection to hand-loading a few materials' textures but, as each tree has a dozen texture sets with ~60+ texture files, I'd have to spend a day in Poser material room, then break out the migraine pills...

FWIW, these models do not auto-load textures in 3D Paint, or Autodesk's own FBX Review. Author was not happy to hear that...

Tangential, are there any free FBX editors that could conveniently tweak such paths ? I've tried converting simple FBX models to 'FBX ASCII' and editing their paths with Wordpad, but re-saved files fail as 'corrupt'.
