Ability to change Zip Code wording

I would find it beneficial to be able to change the entire site's referencing from Zip Code to Postcode.

Currently, in my case, when upgrades are carried out, all referencing to Postcode will always revert back to Zip Code. This results in a request for support each time, requiring amendments.

For a long time, in site admin, the ability to create/choose a display name for Country, Region, State (which I have changed to County), and City (which I have changed to City / Town) has existed, but never for Zip Code.

Perhaps there's an operational reason why not, but if there isn't, it would save repetitive time and effort for all concerned and enhance/personalise the user's experience.
