[Pharo-project] System -> About in Dev images

Hi folks: If you take a Dev image and go to " System->About " you get something like: PharoCore1.0rc1 Latest update: #10505 However, I would like to show something like this for example: Pharo1.0-10505-rc1dev10.01.1 PharoCore1.0rc1 Latest update: #10505 Do you know how we can change this? How can I set that name when building a PharoDev image? Is this related to SystemVersion ?? We need to have this fixed for the official 1.0 release. Cheers Mariano
