ON HOLD Audit: Add ability to take a heatmap snapshot for first Supply Alert published, call it “Supply Impact Analysis” and save to Supply Alert files.

Adding functionality so user can save snapshot of current selection (SKU Heatmap). The snap of the table should be saved and automatically stored in repository (like using functionality of "Attach doc")

To be confirmed: can we easily store it as excel file?

The name of the file should be: "Supply Impact Analysis YYYY-MM-DD"
