WooCommerce Subscriptions Email Variables

Hi there,

I am working on a site which uses WooCommerce Subscriptions in addition to Follow-Up Emails and they have noticed something with the reminder emails sent to customers 1 week before their subscription renews (these are set up through the Follow-Up Emails extension).

It basically says:

`Dear {customer_username},

We are writing to advise you that your payment for your next purchase of

{item_names}

will be taken within the next seven days.`

The issue is that the {item_names} email variable (taken from here https://woocommerce.com/document/email-variables-and-merge-tags/)shows the entire order from when the subscription was originally purchased, so it includes one-off purchases as well as the items on the subscription. As a result, it might be misleading to the customer that they would be charged again for items they only made a one-time purchase for.

Is there an email variable available that only shows subscription item names rather than all names that I can use instead here, or alternatively, a way of making this possible otherwise?

Thanks

Jon
