Convert sector files (.sec) to OTBM?

I havn't been able to find any data on 7.6 sign text/books anywhere, so I'm wanting to extract the data from the .sec files included in the Cipsoft leak. But the editor doesn't load them all at once, only when you scroll. This means I would have to scroll through ALL of the levels to fill the minimap and save all the sectors as one OTBM. This would take quite a while...

So I'm just reaching out to see if anyone else has a tool that can do this, or is willing to send me a copy of the OTBM.

Thanks!
