Feather Document Link widget designer doesn't expose an advanced view

[sitefinitysteve]

We need to migrate old widgets->mvc and instead of searching through piles of docs, the most accurate way would be to just put the documentID into the documentId field from the old->new, but the new designer doesn't seem to have an advanced mode.

The only way to get advanced mode it seems is to:

1. Drop DocumentLink Widget
2. Edit
3. Select a dummy doc
4. Click Okay
5. Selected doc UI appears, this DOES have an advaced button
6. Click advanced
7. Click Model
8. Put in the docID
9. Save\Publish

Quite a few steps here...

Could also maybe even be solved by allowing us to search by ID in the top right search field.
