In my Umbraco 7.3.4 installation I would like an other view for adding members to my page. The MultiNodeTreePicker is restricted to allow only one type of members. ("member type" in my screenshot)

Right now:

1. Press the add button
2. Start searching for the members.
3. all the member types are shown in the list, but can't be used

Ideal:

1. Press the add button
2. Show all the members of the selected member alias or search hide all the other member types from the list (like "member type 2", "member type 3")

Thank you!
