Possible to add multiple calDAV-Accounts?

[pHJosef]

It would be great to have the option to use more than one calDAV-Account to sync for example multiple nextcloud accounts. When sharing lists with different teams on different platforms, this is essential.

For me this doesn't work yet (linux app on ubuntu). Did I miss something or is it not possible?

Thanks in advance and thanks for the great work so far!
