Colorbar position inside layout

having done (the heatmap is the 4th plot down in a 5x2 layout)

cbar = Colorbar(f[4, 1][2, 1], vertical=false,height = 20)

I get something like this:

Is there a way to get the colorbar to sit just below the heatmap, using the whitespace created by the axis to the right that the heatmap is aligned to?

just put the heatmap at f[4, 1][1, 1] and then also set flipaxis = false on the colorbar
