componentclass for a subset of descriptions

[Norbert Hartl]

Hi, 

I have an Object which has descriptions for:

Route
- name
- text
- track
- locations

I need to edit track and locations at the same time. That
means I want to have a componentclass for those two fields.
Usually this would be an extra object containing of those
two. But I like to avoid to build an extra class just to
be able to edit the fields separate.

Is there a way to arrange the descriptions to accomplish
that? I tried to build two subsets of the Route descriptions
(name, text) and (route,track). But it isn't possible to
add the one container to the other, or is it?

thanks in advance,

Norbert
