Rename frames to numbers in order without plugin

Hello, I am trying to build a presentation and we need to rename all of the frames to numbers in numerical order (based on placement in file: left to right, then top to bottom) 
We are not allowed to use 3rd party plugins. Is there an easy way to do this using built in tools? 

Secondary question: Is there an easy way to link all of these screens from one to another in order for the sake of a prototype presentation. (Rather than exporting to Figma slides)
