Merging Team slides into a single module

I'm working on a team with two of us and we've been developing parts of a module separately. So far, we've been uploading what we're working on into Team slides and then one of us merges the slides into a sort of master module.

My question is... is there a simpler way of merging the slides into this master module without having to recheck all the navigation points, etc.? It would be great if there was a function similar to the replace picture where you can right click or replace the slide with the updated one.

Love to hear your tricks or tips for this situation.
