Plus42 Equations, Preview Release

I'm a bit confused about directories in Plus42. Can I do the following?

- Make a directory
- Store some programs in the directory
- Stay in the HOME directory
- Assign one of the programs in the subdirectory to a custom key so I can run that program (shift-custom -> assigned key) while in the top level directory

I know I can do the first three steps, but I'm unsure of the last one. Reading about the program references, I think it might be possible, but I'm not quite sure. Any ideas?
