Several price lists

Hello. Thank you for preparing an excellent product that has been helping us out for many years. We have purchased many premium solutions, and we really need them.
At the moment, a new task has appeared that requires a thoughtful approach, please help me on how to do it correctly.
Our website for clothing repair and sewing has a large price list, which consists of many tables.
https://rematelier.ru/tsenyi-na-remont-odezhdy/
It contains many sections: skirt, trousers, jacket, and so on.
The price list looks like this:
[table id=1 /]
[table id=2 /]
[table id=3 /]
etc.
On the target (landing) pages, we offer customers to see the prices for this type of service, and therefore we insert the shortcodes of the required table into the text editor
On the “Skirt Repair” page, we have [table id=1 /],
https://rematelier.ru/remont-platya-yubki/
On the “Pants Repair” page, we have [table id=2 /], etc.
But there is one problem.
Sometimes we hold promotions, and in this case, our prices become 20% lower. To do this, we have to manually fill in all the tables again. This is very tedious.
It would be great if the site had a set of tables (price lists) with different prices prepared, which I could activate at my own discretion when needed.
For example, during normal times, we use Price-1 with high prices, and during the promotion, Price-2 with low prices.
And it would be great to switch between these price lists. And so that the target pages would pick up the required price table according to the current price list.
Please tell me how to do this?
