Find or Replace across multiple user selected directories

I am enjoying PyCharm for my Python 3 work.

I have been using Komodo IDE.

There is a feature in Komodo IDE I am not finding within PyCharm: The ability to select multiple directories user may wish to find or replace phrases across multiple user selected directories.

For example, I may want to find or replace phrases across multiple separate projects.

I tried using "All Projects" but it only works on the current project, and not other known projects.

I tried using "Directory" but it only allows selecting a single directory, not multiple specific and distinct directories.
