Any way to make the autoselect prefer "I" instead of "u"?

All too often I reread my text to see that the letter "u" was placed where I definitely meant "I", which naturally changes the entire meaning of the sentence. I never use "u" as a diminutive of "you". I can long press it in my pr edict bar and tell it not to predict it again but that does nothing for single letters.

Is there any way to manually assign prediction priority so that "I" is always suggested before "u", no matter how precise my swiping may be?
