CCS/TMS320F28379S: CLB project: indicate how import from exemple, but not to add into existing project

Tool/software: Code Composer Studio

Hello

I try to understand this module.

Then, my first question after read documentation is:

Quickstart guide indicate how create a project using the CLB tool. The method is to import an existing project from the C2000ware (Empty project or simple exemple)

But now, I want from my current projet (which have not clb) add the functionnality to use the CLB block.

How can I add CLB tool into existing project which have not yet?

Thank
