Out of stock

Hi everyone, I search for this topic I couldn't find anywhere, and I am sorry if I am repeating this.

This is what I would like to do.

After “In Stock” is zero and I choose the Availability option of “Out of stock actions” equal to “sign up for notification

Then in the product page It shows the “out of stock” and also the option for entering email for notification.

I just wonder if is there anyway we can show the “Avail Since” date also next to email notification so customer will have some sort of idea when to except the product to be available.

Thank you,
