Get Selected Fantastical Item

Has anyone got a way to get the selected Fantastical item (or items if possible) and pull all that info into keyboard maestro to be processed?

I get a selection of events every week, all with unique names in a selection of calendars (that also share items that don't need to be processed), each of which need an extra 'prepare' item added directly before it. At the moment, I just do each manually albeit with the help of some text expansion, but it would be great to be able to pull them all into Keyboard Maestro that could do the required processing.
