Screen Customization - Sub-project Field

Hello,

As I told you before, I am using the screen customization plugin. I really appreciate it !! I created some projects' templates. I would like to use them as a sub-projects. When I click on the sub-project field, I want that only a particular type of projects (Not all) to appear. Is that possible ? I really need that for my work. I hope you understood my question. If I need to modify the code, could you give me the name/location of the source file? Thank you very much for your return.

Best regards

Hello,

I will take a use case :
- I have 2 projects and 2 templates as below :

- I want to create a new project (project 3) by copying the template1 :
--> As I want to put this new project as a sub-project of another, I click on the list-field "is sub-project of":

--> As you can see above, When I do that, all the projects appear on the list (even the templates).
My question is :
Is it possible to hide in this list the templates (I don't want them to appear) ?

I have 3 other (simple) questions which are not related to the topic above :
1) Is it possible to not increment the WBS value for project's template ?
2) How can I initialize the first WBS value at 1 (my wbs values begin at 232 after I have deleted all projects in the database) ?
3) Is it possible to lock a type of project to a type of profile?

I thank you again for your availability.

Best regards
