Indeed. It would be nice to be able to configure your own ics links.
I would like to be able to create a calendar for the teams I play in and a separate calendar for some of the teams I manage. This way I can have different colors for different responsibilities in my calendar.

So: One link to rule them all (most people will use this one) + configurable links for which the user can select the teams that should be in that ics link

Agreed, I would like to see a way to separate the teams (or people) when syncing to another calendar. I see that I can separate them out in the Teamstuff app and web page, but I would like to import them as separate calendars in google. I organize many teams and clubs and could use this to share schedules with all of them, but if they import as one calendar in my gmail account, it becomes useless to me. I have separate calendars in gmail for each of my children and importing all of their activities as one calendar defeats the purpose of multiple calendars.
