Select which of my emails/aliases a calendar invite is FROM
Option list in each appointment that lists my emails to choose which one is the 'from' address for the appointment.
POSSIBLY COOLER: Option list of default "from email"s for EACH CALENDAR I set up!!! - Every appointment set up with that Calendar/color will be from the configured alias/email

Several scenarios: 1) I want to minimize the use/footprint of my main account email 2) I use proton calendar as central calendar for several of my personas/emails - so several meeting schedules for different groups centrally listed (for me) in proton calendar.
Not trying to get greedy - but possibly better feature is tie a default email (selected from my email list) assigned to each Calendar i set up (possibly more useful!?! than an option on the events themselves.)
