Support for multiple Calendars in one ICS file?

[JVTEAM]

I combine a couple calendars into one for another use. When I try to use this plugin I get this error.

Are you OK with having both calendars show up as a single calendar in HA? I ask because anything else would require either a funky configuration, which relies on the order of calendars in the ICS file remaining constant (probably not a big deal), or really twisting the code around to do it. I won't go the latter route, and I'm hesitant to do the former -- I expect this is a very unusual use case, and I don't want to make my own maintenance problems harder. :)

Please note that anything will be a while, as new features are a low priority compared to what's in the TODO.md file.

Yes, I combine them because I use Dakboard on a wall tablet that won't allow more than one calendar on a free account....so I manually combine them all via a script. I have no need to keep them separate on Home Assistant.
