I would have thought it was possible to do on most DSLRs. My cameras are Nikons D3 and D4. Have a good look at the instructions for your model as the system really works well.
Using the camera menu the in camera name is _AAA0192 or _BBB0192. It is then converted to the long file name using PM dropping the first 3 characters including the underscore.
I don't know where you are but in the UK there is a new law on its way which legitimises the use of orphan images where the metadata has been lost or stripped out by Facebook etc. However, with your name in the front of the file name, mine is fairly short, you are still traceable unless somebody alters the file name and claims ownership in which case that is direct theft.
I hope this helps.
