Attach arbitrary data to jwplayer setup options

Question

I want to be able to do the following:

jwplayer("myElement").setup({
    ...
    myoption: 'myvalue'
});

and then I would like to get the value of myoption in some way. For example:

jwplayer("myElement").options.myoption

Is it possible to do this?

PS. Don't ask me why I want to do this. I know that there are other ways. But I am asking about this way.
