Here's my attempt for a engine helper-mod. It's based on Dr_Newbies and TdlQs work.
https://modworkshop.net/mod/35686
With my version, you're able to pick up the notepads.When done, they get moved to the Whiteboard in the basement. When you've found both notepads, the correct engine will be marked.

I'm not an experienced coder so I struggle with this stuff, but I got it working.

Feel free to expand and add to this mod.
