Inquiry about Discount Rules

Hello!
Thank you for developing such a great plugin which is fulfilling my needs for free of cost! I created 2 category discount rules and was wondering if there’s a way that I would be able to show them on our sales page which has this shortcode:
[sale_products]
As the sale tag is showing on the products when I check them in the specific category page but the products aren’t showing up in the Sales page maybe there’s a separate shortcode for tha?
Secondly, is there any way to disable the use of coupon codes with the discount rules?

Thank you!
