Is there a way to sell custom Google Sheets templates on Squarespace without having to email each customer's link directly?

I sell custom Google Sheets templates on my site and it is a pain to email each customer a link. Is there a way to automate this on Squarespace? I know I can change the custom message sent to customers after purchasing, but only per product type (digital vs physical, etc). I sell multiple variations of the digital and offer services and physical products too. 

I'd like to be able to just link them to the view-only master template with instructions to copy after purchase. Is there a way to do this? 

Many thanks in advance! 

Looking into this as well. I have been getting ready to sell my Notion templates on my site, but it's a little wonky because I don't want them to start sharing the link with others... 

This is a great question, following!!

That is so smart. Why didn't I think of this?!
