Disable case sensativity in auto-correct word completion?

Is there a way to disable the case sensitivity in auto word complete? I’m physically disabled, and intended to use auto word complete in conjunction with a word list of common terms for what I’m writing, but I can only use it if the words match the capitalization of the words in the list.

you may extend your list with the likely capitalized variants, e.g. Case Converter Online - AppDevTools
