Change Jenkins concurrent job workspace naming

Question

Can I change the way Jankins names the workspace for concurrent jobs? Currently it uses the @2, @3 when running concurrent builds. I would like to change the "@" to another character. Is this possible. It is causing problems further down in my jobs.

Workspace created for concurrent job #2: in workspace /devsrc/jenkins/workspace/CKPT_vw5.2_ubuntu@2

Further down in build script: The environment variable II_SYSTEM contains characters that are not allowed. The path should only contain alphabetic, digit, period, underscore and hyphen characters. + [ ! -f /devsrc/jenkins/workspace/CKPT_vw5.2_ubuntu@2/ingres/files/config.dat ] + exit 1

I didn't test this before posting, but I've used these types of parameters in the past with no problems. See features controlled by system properties. In there, there's one to change the @ to something else:

"hudson.slaves.WorkspaceList" (default value: @)

When concurrent builds is enabled, a unique workspace directory name is required for each concurrent build. To create this name, this token is placed between project name and a unique ID, e.g. "my-project@123".

In Ubuntu, I would edit /etc/default/jenkins and add this to the "JAVA_ARGS" property and say use "A" instead of "@". And of course you'll need to restart Jenkins.
