Sorting on runtime calculated price value? - elasticsearch

Question

we have day prices in our index. When user search for 7 nights we show the total price (7*nightprice = totalprice). We want to sort on total_price value.
The process and issue.
First we call our Index API to search appropriate accommodations by checking availabilities, restrictions etc. After that we get accommodations from our API, we pass searched accommodations ids to our Prices API to get they dynamic price. We are using ElasticSearch custom DSLs for our search. Now, we need to sort accommodations based on dynamic prices while keeping pagination on server side, but we can only sort accommodations that are visible on our first page because of dynamic prices are calculated in a separate API.
First call (Index API)
