How to change Flash Builder default src folder name

I know you can change Flash builders default "Main source folder" by right clicking 开发者_StackOverflow社区on the project properties and going to the "Flex Build Path"

...but how do you change that by default for all new projects? I prefer the folder name "src_flex" rather than "src" when I create my projects.

You can do this for PHP in "PHP>>New Project Layout" preferences but I don't see anything similar for Flash Builder or know if there's a (hidden) file I could edit to do this.

Thx!

Hmm, I don't think it's possible. You can fill a request for that on http://bugs.adobe.com/jira/
