Chord symbols & Rhythm

Hello,
I was wondering if it is possible to let the chord symbols play back in an independent rhythm, regardless of the melody rhythm.
For example: if the melody rhythm is four crotchets, would it be possible to let the chord symbol rhythm play back somethin like crotchet, quaver, quaver, crotchet quaver, quaver or crotchet, dotted quaver, semiquaver, crotchet dotted quaver, semiquaver?

If so, how can you achieve that?
If that were possible, it would be a great help to me.

Thank you in advance for any comments.
