Possible to notify customer of “pending payment”?

I’ve been trying to figure out how to send an email to a customer who has gone to the payment page but never completed the payment.
As long as an order is in “pending payment” there is a direct url on that order page (just above the order status), named “Customer payment page →” and takes you to “https://[YOUR_SITE]/products/checkout/order-pay/%5BORDER_NUMBER%5D?pay_for_order=true&key=wc_order_%5BRANDOM_KEY_VALUE%5D”. I would like to automate this, so that when an order is placed, but not payed for (i.e. goes to status “pending payment”), it sends out an email to the customer reminding them of their cart and also notifying that the payment still hasen’t gone thru.

This functionality is already in woocommerce, under the actions drop-down list you are able to resend the invoice. And with some simple template changes to the email template already existing “if statement” for pending, this can easily do exactly what I want. I’m just curious as to way there isn’t an option to automate this? Because now I would have to check every minute to see if an order has been made and if it is in “pending payment” mode. If it is, go in and re-send invoice to customer as a friendly reminder that their products are being held for theme. Then I can set a time when to re-release the product stock if the order isn’t fulfilled.

I’m also looking in to “abandoned cart” functionality, but to my understanding so far, that is something else (as it doesn’t handle the different order statuses, but is more of a time based feature that also captures orders that never went to the payment page).
