Research direction
Start by examining how QK REP (repeat key) is currently implemented, likely in tmk core/common/action.c or quantum/keymap extras.c. Also review the key override feature (quantum/key overrides.c) to understand how overrides map to keycodes. The goal is to modify the repeat logic so that it repeats the override output instead of the original key when a key override is active.
