I can overlay a lot of indicators in the main chart window. For example, I can have a variety of moving averages all functioning without problems. Therefore, I know that it is indeed possible to overlay multiple moving averages in the chart window.
However, when I add an indicator, such as MACD, I can display only a single indicator in that subwindow. I would like to overlay a second MACD in that same window, but see no settings that enable this feature. I tried drag-and-drop without success, as well as as copy-paste.
I then expected that it would be possible to access that existing subwindow by code, and assign a second MACD indicator to that window. However, I found no way to do this. Is there an example available that demonstrates how to accomplish overlaying indicators in the same window? If the answer is "it is not possible"

, then how is it possible to do it in the main chart window
