Portafurnace in more areas!

There's almost no point in having this item since it only works in non-expansion field areas like Konschat/Vulkurm/Rolanberry etc. Please let us use this in Aht Urghan/CoP field areas(Caedarva/Lufaise etc) and dungeon areas too. Too many times I get asked to craft something in the field and I have to wait till after an event to do it. Synthesizers can use crystals in any zone, why can't we use portafurnace in at least any field area(i can understand why we can't in dungeons since being able to freeze your buffs or debuffs[doom/poison] anywhere could be exploited)

Yeah, that never made any sense to me. The main place I would even want to use it is in dungeons and the like while farming non-stacking materials.
