That's the only way guys, use midi for this. The reason is RT's are audio files, you can't put a sustain envelope on an audio file like you can with midi. That envelope will sustain it in midi as long as you want. It's called ADSR for Attack, Delay, Sustain and Release. It manipulates midi data but is useless on audio files.

This is one of the big limitations of the RT's when using chording instruments like synths and piano. Remember these tracks are prerecorded. The player in the studio doesn't know what chords you will be using. If he recorded that part using those changes then sure he would sustain the common notes or use the sustain pedal on the piano but without that info you're going to hear those chords as separate sounds.
