movie's number of disks

[wwwXM]

Is it possible to change the maximum value of disks number for a movie? I know it is a strange question (is any body having a movie on more than 99 media?) but I use this field to count copies of a movie I made.

It is already corrected in the future version 3.5
When I designed that, I thought that 99 will be enough but since some people use it for other purposes I raised it to 9999
