Increasing stack size via technology

[Cen]

If/How would it be possible to increase the stack size of an item from a technology?

More specifically I would like to add +1 to the stack size of promethium asteroid chunks through an infinite technology, but I'm unsure as to how to go about it

Stack sizes are part of the item prototype and can't be modified run time.

Closest you can do (without a bunch of weird scripting jank) is make technologies for compressing multiple promethium into a new item that can be decompressed back into multiple - ie like several crating/boxed mods do for regular items.

Ah, well thank you anyways for the info on how the prototypes work
