Dear Drupal Community Members,
I have started using Drupal not long ago. I'm using Drupal 6.16; CCK 6.x-2.6.
At the moment I'm learning CCK and have encountered some problems with nodereference field type settings:

1. In the section "Advanced - Nodes that can be referenced (View)" view arguments need to be supplied in advance, but I need to provide arguments at create content stage to shorten the list of selectable (I am using selection list widget) items.
For example: Referenced node (content type) has one to many relationship with some other content type, let's consider room and building. I have made selection view providing filter Node.type = "room"; relationship to building content type and argument to specify building. So in this content type field "room" I am referencing room for some building, different each time. How can I provide argument "building" at create content page?

2. Is there a way to supply input for one field as a view argument for the other field at create content stage?

Please advise where should I look, or any module available for this.
