Is there anyway to truncate the whole absolute path when logging?

Right now, my layout for logging is

"layout": {
   "type": "pattern",
   "pattern": "[%d{yyyy-MM-ddThh:mm:ss.SSS}] [%p] %c %f %l - %m"
},

But the filename option is printing out the whole absolute path to the file. I would like to have possibly the option to see either
filename.js OR .../folder/filename.js
