Product Bundles

We need to add custom validation logic on the bundle product, in our case, it is required that the total qty from all items together will be in steps of 6 (this is our box sizes).

For example: 6, 12, 18.

We seen that there is a property called validation_messages in the add-to-cart-bundle.js file but it is not accesibble from the frontend.

Please add an API for that property so we will be able to add custom logic based on the validation logic in the plugin.
