IFTTT google calendar and meeting notes

[jinesch 0]

There is a nice feature in IFTTT to create an Evernote note 15 minutes before a meeting that you enter into google calendar with @en in the title. Does anyone know whether this 15 minute rule can be changed to another time? I would like to prepare my meeting notes a bit in advance. Ideally I would like IFTTT to create a note straightaway when I enter a meeting with @en in my google calendar, but not for other meetings I might add to google calendar. Any ideas on how to achieve this? Thanks.
