Thank you for your reply, Rocced!
We accept feature requests over emails too, so there are more than 2 but still little on ternary associations.
Please feel free to send us more of the feature requests or any feedback you have, it may not be added soon unless it is already planned or we receive many, but at least it would be added on our user-wish list so that allows us to know what our users want.

Thank you.

Cheers,
SJ
