Importing FBX

I'm unable to automate fbx importing, from the documentation I figured something like this would work, but the file explorer dialog keeps opening.

import zbrush.commands as zbc
zbc.set_next_filename("c:\\MyModel.fbx")
zbc.press("Zplugin:FBX ExportImport:Import")

Folder Creation

I want to automate folder creation and naming

zbc.press("Tool:SubTool:New Folder")

This correctly calls the "New Folder" button, but how can I automate what gets typed into the popup dialog? Can I create folders with a specific name without user typing the name?

Subtool Renaming

Is there any way to rename the subtools inside a tool? I guess this is a similar question to the Folder creation, if I can fill the text in the popup from the ui button, this would be easy.
The closest thing I got was renaming just the first subtool by renaming the tool itself:

zbc.set_tool_path(zbc.get_active_tool_index(), f"MyFirstSubtool")

Is there a way to fill or interact with these popup dialogs?

Thanks in advance
