It would be helpful to be able to select a set of rows and, rather than only seeing the attachments of one row, the first selected, it would be useful to show ALL attachments for each of the included rows.
E.G. If I select row 1, and shift-click to select down to row 5, current behavior will only show Row 1 in the attachment panel, however it would be useful for it to show the attachments included in Row 1, 2, 3, 4, and 5.
