Hi everyone!

Hope you can help me with this issue:

I have two CTP in my site:

1. deck
2. tournament

Then, in CPT Deck I have a custom field of type object in which you can select one of the CPT Tournament.

CPT Tournament have a custom field of type date.

My problem is that I would like to order the CTP Deck Archive by the date of the Tournament it is linked to.

I would like to achieve this through filtering the pre_get_posts hook.

Is this possible?

Thanks!!!
