Slice: only the axes you choose

On a grid of meshes, slicing every one would bury the two you care about under sliders and strips. The Axes to slice radio in the Slice menu picks between All axes and Selected axes; choosing the latter lets you click axes on the figure to add or remove them (the menu’s Choose axes on figure re-enters that mode, and Esc leaves it). Axes left out stay plain heatmaps, and Link all matching axes couples only the chosen ones.

To start with a selection, pass the axes (or their indices) as axes. Here a 3 x 3 grid of mode patterns starts with just the top-left and centre modes sliced; click any other panel to bring it in, or click a chosen one to drop it.

options={"slice": {"enabled": True, "axes": [axs[0, 0], axs[1, 1]],
                   "link_all": True}}

This figure has 9 panels — too many to usefully embed at a fixed size.
