I use fd-footnotes plugin, that inserts the footnotes in the text if it finds some shortcodes (like [1. my footnote]) in the text. But I would like it to process the content of some custom fields as well. The problem is that the plugin processes the content of a page before I add the custom field text to the content.

So the question is how to either a) change the content before the plugin runs; or b) pass to the plugin the content with the custom field text added.
