On Screen Keyboard file KVK with two characters

In my keybaord layout, vowels have two/three outputs depending on the previous keystroke.

Is it possible we can display two or three characters in two/three corners of the key display.

With distinct color, it will be helpful.

If this doesn’t exist in the current version. I shall submit a feature request.

You may not be able to add more than one character on a key with distinct colors.

You may want to write a documentation on how the vowels are changed/transformed and include it in the keyboard package.

Thanks. I will do that instead.
