Currently, drawing objects such as horizontal lines and rectangles can be set to Global so that they automatically appear on my other charts for the same instrument.
However, these global objects do not appear in the Heatmap, even though the Heatmap itself supports the same drawing tools.
It would be very useful if the Heatmap participated in the same global drawing-object system as regular charts. For example, if I mark an important support/resistance level or zone with a global horizontal line or rectangle on my footprint chart, I would like that same object to automatically appear at the corresponding price/time location on the Heatmap, and vice versa.
