First of all I apologies I did not know you open the issue here I think it can
you can implement like so

const multer = require('multer')
const storage = multer.diskStorage({
destination: (req, file, cb) => {
  const { userId } = req.body
  const dir = ./uploads/${userId}
  fs.exists(dir, exist => {
  if (!exist) {
    return fs.mkdir(dir, error => cb(error, dir))
  }
  return cb(null, dir)
  })
},
filename: (req, file, cb) => {
  const { userId } = req.body
  cb(null, UserId-${userId}-Image-${Date.now()}.png)
}
})
const upload = multer({ storage })

expressjs/multer#556 please check this issue for more info
