NUX Synchronise Page Selector from Line Item



I'm trying to configure my NUX dashboard to update two separate cards based on a line item list selection.

In this example (see attached), I'm updating the Current Period from a field card. This in turn updates the filters on the Group P&L grid card as it is linked to a saved module view.

However, I also need it to update the Commentary field card. The field card was chosen because it is the only way to present multiple lines of text. However, I'm unable to link a field card to a saved module view or apply filters, so I've had to use a page selector to filter the field card.

Is there a way in the New UX that I can either a) publish multi-line commentary in a card that can apply a filter or b) synchronize the page selector when updating the Current Period line item list selection?
