Globally unlock mulitple OTLs?

[kev2]

I have an FBX with many embedded locked OTLS. Is there a way to globally unlock them? I'm trying to change the texture path on a shader for the OTL geo with Pre-Flight but can't b/c the OTLs are locked other than import the FBX with unlock on?

You can do that with python (if anyone knows a simpler way, let us know)

n=hou.nodeTypeCategories()
for i in n:
    for j in n[i].nodeTypes():
        k=n[i].nodeTypes()[j].instances()
        if len(k)>0:
            for l in k:
                if l.isLockedHDA():
                    l.allowEditingOfContents()

I've attached a file with a null that execute that code with a press of a button
