Automatically add hyphens when words break across a line in Large Print documents

Since our content is produced by upscaling existing English RTFs, our large print output can break awkwardly. The most concerning is when a word is too large for a table cell. We would like for the Large Print project/TDF to automatically add a hyphen to make up for grammatical issues that occur in the font upscaling.
