I'd like to be able to run custom agent commands on the top level block taking into AI context all the subitems and elements in the block. This will be very useful for running the new background custom agent command in the table format. For example, in the attached screenshot, I should be able to run the custom command on the entirety of "Saving La Villa..." and all it's underlying elements. Once the custom agent is done, you could place the output as the last element of the this block.
