Let me see if I can explain this a a manner that is not insulting.
One or two coders have been willing to assist you with any number of requests for custom code that extends beyond the core functionality of the software. That's great and that is their prerogative. There is an invisible line between free assistance and paid work. My (or anyone else) providing what should be paid work free of charge steps on the toes of people like Glenn Vergara who are trying to sustain a living by coding for vBulletin 5. I'm not willing to do that. It's not personal against you or anyone else. My conscience won't allow me to provide free what would be and should be paid work.
Having said that, and seeing as how no one else has responded to your request, I suggest you contact Glenn at his website
https://www.vbmods.rocks and inquire as to whether he might be willing to do the coding for you and if there would be a charge.
