Trying to use cursor buttons with modifier WASD

Hi!

I want to use the cursor buttons what was made for controller users mainly. For me it seems more efficient to use my keyboard buttons than my mouse for menu navigation. I wanted to use Alt + WASD buttons to navigate in menus and used F as confirmation button.

The problem is if you keybind cursor buttons to any modifier and any buttons of the WASD, if a menu is active, the cursor appears but does nothing and you stop moving momentarily. It seems the game gets input for cursor while you are just moving without modifier. Is there any way I can use WASD for movement but Alt + WASD for cursor? It would be such a QoL change for me.
