Extract Block Filter: Extract Single DataSet not MultiBlockDataSet

Is there a way to extract a single block from a multi-block dataset using the Extract Block filter?

Whenever I use the Extract Block filter, it returns a multi-block dataset but I need to apply filters that cannot handle multi-block datasets.

I think the best you can do right now is to use the Extract Block filter to get the block you want and then use a Merge Blocks filter to make that into a single unstructured grid. Otherwise, a Programmable Filter is probably your best bet to do the extraction in a single shot.

We shoud modify ExtractBlock to actually extract the block when a single block is selected.
