For a journal, each value in the calculated availability is calculated independently, based on the lowest and highest value of the items, even if they do not come from the same items.
I.E: if we have the following items:
2022,1 to 2022,4 and 2023,1

in Summon the availability is displayed with:
from:1 2022 until:4 2023

instead of
from:1 2022 until:1 2023

We would like change the summary calculation in availability.
