PS The rubber size cannot be changed temporarily when the rubber tool is switched temporarily.

In PS, I temporarily switch to the eraser tool by pressing E, but at this time I can't adjust the eraser size. When I press the shortcut key, it will automatically change to adjust the brush tool size. How can I solve it? In both sai2 and csp, it is possible to temporarily change the tool size when switching tools temporarily. Why can't PS do this?
