Designated Spots on Orders Heat Map

Hi,

I was curious if it was possible to have "designated" points of interests on a heat map visual. For instance in the picture, the heat circles are orders. What i would like is it possible to have another "heat circle" or any icon i could put on there to showcase where the warehouse locations are? So where the arrow is pointed would be a icon showing a designated point of interest. Let me know if it is possible. Thanks!
