3/4 Digit Grid Square callout for Radio Contact Reports

[mikolajcap21]

How would I go about making contact reports in game display three/four digits?

For example all contacts in game are displayed with only 2 digits such as AL-54, but I want to make it so the report reads something like AL-5432.

Not only this would be more historically accurate as contact reports in real life were sometimes provided with 3 or 4 digits it would also make it slightly easier for players who play with "map contact updates" disabled or the Cruel Sea Mod which disables the radio contact icon.
