CMS Number field - specify padding / format?

How do you specify a number with a certain number of digits in the number field:

e.g. To set a four digit number 0000 using either Integer or Any format truncates to a single 0.

Likewise specifying 0001 truncates to 1.

It’s fairly standard to have a 0000/00000 in terms of something like a project / item numbering system for test purposes.

Unfortunately that’s not possible. You’ll have to use a normal text field instead.
