WP site pricing matrix?

Question

Web development

Website of educational courses, 10 courses * 5 forms of education = 50 prices + the same amount if there are discounts.
Prices appear on different pages: in the course description, order form, general table and landing pages.
If there is a discount - the new and previous price with the "discount" label is indicated; in the order block, a countdown timer is attached to the discount.

Setting prices manually is not an option - prices change, discounts appear / disappear.
How to do price management in one place? Maybe there are plugins?
Ideally, I would like something like this table:

You, I think, are unlikely to find a ready-made plug-in - rather specific requirements. But making such a plugin is not difficult, data management can be done through options on a separate page, inserting prices into pages / posts can be implemented using shortcodes. For a normal programmer work for a maximum of 5 days.
