Customize Overview in Dashboard

Hello together,

is there a possibility to customize the overview page on the dashboard?

Background: We use the session-entry "host" to represent a machine. A host or machine can have one or more ways of accessing it (i.e. ssh, web browser, some command line interface / 3rd-party application, ftp) all possibly with different credentials and sometimes ip adresses. The overview in dashboard is good and shows something like this:


Unfortunately there are only some sub-connections possible. However we need to add some additional information like credential-entries, documents, links, ...
Obviously the folder/group-entry suits better for that, but then the overview is not usable:

I know that there is a column chooser, but username is not enough and the view is not structured enough.

So the wish is that the overview in the dashboard is configurable for each entry type (and particular entry) so that i.e. we can have a similar view for group as it is already for session.
Another possibility: allow all entry types as sub-connections. :-)

Thanks for any answers / ideas.

Regards,

Thomas
