Add variables to shortcodes

Hi, congratulations on the plugin, truly revolutionary. Would it be possible to add variables to the shortcodes? For example, I have a snippet with a shortcode call:
[fluent_snippet id=”xx-xxxxx”]

It would be interesting to insert some variables, so for example:

[fluent_snippet id=”xx-xxxxx” custom_par=”XXX”]

To be recalled within the snippets. So, custom_par becomes $custom_par and I can use it easily.
