Macro to Reset Selection Tool to default

Hi All, I’d love to lock the selection tool so its always on Default, or have a macro that i can assign to a key which just makes it that particular tool (Main selection tool). I’ve set up other macros before (IE: to arm and disarm track monitor and record states for all track types", but i cant see how i can use the same method to change a tool option.

Any help would be appreciated. This has actually bugged me for a couple of years, and every day i get caught out with the main tool switching, because i type faster than i think. Until i get a preference to disable it, i’d love some help to get around it!
