Hotkey to change between languages

I have two languages but English have two variants(US and UK)
How can I switch only between English and the other language(when pressing the shortcut to not switch between all 3 but just between English(US) and the second language)

Click the language icon on the Language bar, which should appear on your task bar near where the clock is, and then click the language that you want to use. Keyboard shortcut: To switch between keyboard layouts, press Alt+Shift.

That's not what I mean,when I do that and use Alt+Shift,it does not switches between the two actual languages but it switches between all added language

To put it simple,lets say I add 10 different languages and I want when I press Alt+Shift,to switch only between two specific languages of those 10 languages
The only thing I find is setting a shortcut for each language,I did not find a way how to switch between 2 languages using the same shortcut(Alt+Shift)

you'd have to change it via reg and use a batch to toggle it between the 2 so you can assign hotkeys to the batch and use the same hotkey to toggle between the languages. pretty sure its 5-7 reg keys though. i'd have to look for all of them
