Thanks for the files, garner. It is closed to what I want. I wonder if it is possible to get the preview / image of what currently in the output buffer and keep updating regularly? For example, if I put multiple sequence items in different layers in framebuffer1, I would expect to see a combined output of framebuffer1 in Dashbaord, however, in your sample, it is a preview frame of one item and it may not be taken on-air.
