from my point of view, installing a root CA in the hiearchical trust model
means that you fully trust it, thus it cannot be done automatically, unless
you have a trusted sources of root certificates.

If you trust a set of root certificates, like the ones shipped with your 
operating system or a different application, you could just import them all 
and mark them trusted. Of course you would need to sync this, if the set 
changes on updates.

Some hints about using CMS and S/MIME are here
but this misses instructions how to deal with root certificates in modern
GnuPG versions currently.
