Assuming http://www.backward-workshop.com/fritzing-parts/ isn't what you want, yes it can be done by creating an svg file of the multimeter you want and create a new part. I'm currently struggling with making a simple panel voltmeter and, for me at least it isn't easy, but it is possible (and the folks here in the forum are very helpful!). There are a lot of parts around that aren't in the core parts list so google is your friend.
