Changing a multi-view block

[Siberian 1]

I'm attempting to change the Top-view symbol for a multi-view part using the content builder. When I try to change the actual block for a specific view, how do I make sure that my new block appears in the drop down list of available blocks?

won't it be easier if you use Bedit and pick the block and edit/replace with new one

If you have inserted the MVpart and know the name, it should be easy to do it
