It would be extremely helpful to have a way to enforce an exact number of digits for numeric properties, not just character limits or value ranges.
For example, a business might collect membership IDs, employee numbers, or invoice references that are always exactly 8 digits long (e.g. 00123456).
These aren’t just numbers — they follow strict formats.
Currently:
- We can enable “numbers only” validation
- We can set min/max values (e.g., 10000000–99999999)
But that doesn’t guarantee exactly 8 digits (e.g., 1234567 still passes, and error messages can be misleading).
In the property settings, allow us to define:
- “Must be exactly X digits”
- Or more flexible rules like “Minimum digits: X” / “Maximum digits: Y”
