There aren't any mods currently available that do that, but it is possible to do via hext. However, it wouldn't be as simple as just changing one value. There's a value for every instance this happens... so like one for the item menu, one for the PHS menu. Some menus have several instances at once, like shops - there's one for buying and one for selling. There's probably upwards of 50 or so addresses and finding them wouldn't be so easy if you don't know what you're doing... It's possible, just don't know if it's worth the trouble.
