request: handle lora names like checkpoint names

[brodieferguson]

I am trying to quickly compare loras I've made at different steps. I have them saved in subfolders. It would be great to have an option to have different key types like the checkpoint logic so that I can save just the lora name and not the complete path.

Or alternatively some more general logic to tell it to strip all but the last component from a path so it's generalizable to other metadata. Something like lora_name.strip[/, 0] would output the last text following the last "/", keyname.strip[/, 1] would leave one folder path before the last text, etc.
