Additional Layer/Filing Option under Portfolio and before Program

Hello!

We are looking to add an additional layer of organization to our platform. Under Portfolio (which we call Campaign), we'd like to have an additional layer of organization before Program or Project.

We'd like to organize our instance as:

Book Publishing (Portfolio Name)

Book Title (new/additional layer)

Specific Book Email Ad (program)

Specific Book Social Media Ads (program)

And then specific projects that support each program.

This would make our lives much easier to view. Thanks for your consideration!!
