Possibility to pass variables to caldav.baseurl

[Cyril Mertens]

Hello,

as far as I understood, it is no more possible in agendav releases > 2.0.0 to pass variables to caldav.baseurl variable.
I plan to use radicale and agendav with rights being managed by a file which is created automatically by a script (modoboa provides one) and I need to use a caldav.baseurl which looks like https://mdyomain.tld/%d/user/%u/ where variables are those described here:

It will allow me to easily share calendars.
Is it possible to implement such kind of feature ?

Cheers,
Cyril
