When i click the shift key and select multiple shows, it selects them ok but when i insert a webstream block from the left panel it adds multiple blocks to the show even though both the block and the shows are set to 1 hour.
If i use the ctrl click on each of the markers then adding the block it will add only one.
So i need that shiftkey to let me add one block..not a bunch (usually it ads 3)
I tried to recreate the scenario you are describing but it seems to be working as expected for me. I shift-clicked to select a few rows, on the library side I selected a webstream, and clicked 'Add to selected show'. The result was that only one webstream block was added to each cursor position.
Maybe I am not understanding properly. Can you attach a screenshot of the result?
