Draw heatmap for the whole day instantly(save history of heatmap on servers)

When you start ATAS, the heatmap start painting from this instant of time. You can adjust the heatmap size with the "Bars limit". Unfortunately the real limit is the moment in time when ATAS (or the heatmap) was started, so you cannot draw the heatmap back to an earlier point in time.
It would be great if I can see the heatmap at least of the whole day regardless of the time I started ATAS, because I want to see liquidity areas in the past (at least for the current day).
