KA-50 Larger/longer tail number help

[Neqva]

Hi every. I am curious if its possible to change the number of letters or numbers are showing on the tail number for the Shark? For example I tend to fly with a 3 digit tail number but its only the last 2 that shows. I would like to change it so that all 3 numbers gets "painted" onto the aircraft. 

So forexample the tailnumber on the fuselage reads 123 instead of just 23 if I choose my tail number to be 123.

Anyone knows if that possible?
