Hook on PageTable item save can't grab data from the page it belongs to because it's not added until modal close.

The title sums it up pretty much!

I have a page where I save clients information, and then I create an "assignment" where I can pick a sales person and send them an email (through a hook after page::save) about the clients and this assignments page help me keep track of which salespeople have worked with the client. 

The problem is, when saving through the hook, i look for the client info like this (to send within the email):

$pages->find('assignments=$page');

Where $page,  is the assignment being created.

Maybe I should hook onto a field save? Or save the page beforehand in the same hook? (though i think I don't have a reference from the parent document, within the pagetable add new modal)

EDIT: I have another issue now! When saving the clients page, which has the assignments pagetable field, it's triggering save() in the added pages, is there a way to avoid this?
