'Notepad++ User Defined Language not saving with extension

I set up a User Defined Language in Notepad++ and it correctly loads that syntax highlighting if I open a file with the matching extension. However if I try to Save As, it defaults to Plain Text and tries to save with no extension.

Is there some way to force Notepad++ to use my User Defined Language as a file type so I can save files and have it append the extension automatically like any other file type/language?
