How to show only items in select list that viewers have permission to edit?

I'm trying to make a one-to-many relationship between two content types:
* content-type#1 can have multiple instances of content-type#2 associated with it
* I have the display of type#1 set through views to show a list of all type#2 nodes associated with it.

What I did do far was:
- in type#2 I added a Node Reference CCK field
- I used the Select List widget, which lists all the nodes of type #1 (so the user can associate their new type#2 with the correct node).
- Under Data Settings, I selected "Content types that can be referenced:" (name of my content-type #1).
- This successfully shows a select box of all type#1 nodes when adding/editing my content-type #2.

But what I want to do is limit which type#1 nodes users can associate the new type#2 nodes with. They should only be able to associate new type#2 nodes with type#1 pages they have edit permissions for (not able to add to other people's pages without permission).

So it would be great if the CCK field in type#2 could show only items in select list that viewers have permission to edit.

Is there an argument I can make somewhere, to filter this list?

many thanks!
