Global Parameter of the Type DirectoryType

Hello dear people, 

I would like to define or add a new parameter as global for a pipeline of type DirectoryType as Path. The path (DirectoryType) serves as the directory for all at runtime created files in the protocol .  

In case the pipeline is used by another user, the directory should be determined with a mouse click, and the path should be global. 

I appreciate any response or suggestions.

 

Thanks for your help, 

Raed
