Completion proposal order priority

[cergicd]

Hey there,

I have implemented an code completion language server through the lsp4e. The language server is mapped to the existing "org.eclipse.jdt.core.javaSource" content type. To recreate an similar experience like the java editor, I have installed an jdt language server plugin which is also using the lsp4e. So now every time I request a completion proposal the java proposals are first shown and at the end of the list the my code completion proposals...

My question is:
Can the priority of the completions proposals be configured? So that my code completions proposals are first shown and then all other proposals?

Best regards
David
