Instantiation resource path refactoring hints and tips

Options
Hi!
I'm new to PUN and I was quite surprised how prefabs are instantiated. I was used to unity's way of drag & drop a prefab which I can instantiate by just using its field. This makes it much easier when i rename or move an existing prefab.
The way photon is doing this (path to resource) is quite tricky, as everytime there happens a change, it will break references.
Is there a better way how to manage this in large projects? Any chance to facilitate this with object pooling assets?
