@Patrick68, you can certainly make Drafts parse lines in a draft multiple times. There are many posts in the forum and actions in the action directory that deal with Fantastical, and in ways to process information in Drafts. You also don’t have to combine everything in one action per se. You can chain actions together through the Include Action action step.
You also seem to have posted the same point/question three times on three different threads today. I would suggest you give folks a little more time to ponder your request for assistance.
While you note in one of those that you are “very poor in scritping”, I would suggest that you at least give things a try. You have lots of starting points available, and increasing your skills in this area will pay dividends and open up numerous opportunities for you. You may even surprise yourself, but you never know until you try.
Also, note that when you have smaller, specific questions, that can also open up the option for many more forum users to help you with the questions that you might have.
Hope that helps.
