Customizable meeting title in calendar invite (.ics)

I need to be able to customize the title/subject line of calendar invites (.ics file) so that it's not the name of the type of booking, as TidyCal currently allows, but instead something of my choosing, similar to the way we can customize email reminders using bracketed tags.

Example: I have one booking type called "30 Minute Meeting" and another called "15 Minute Consultation." When a client books a 30-min meeting with me, I want the calendar invite (.ics file) to have the title/subject line, "Meeting: [Client Name] and [My Name]," rather than "30 Minute Meeting," and I want 15-min consultations to say "Consultation: [Client Name] and [My Name]."

At minimum, I'd like to be able to have names in the subject line rather than the booking type!
