How can I edit built-in suggestion?

Idea has built-in if template of: " if() " (no brackets).

I don't like this style, so I wrote if template of:

"if ($var) {

$end

}"

this template works great, except one inconvenience: whenever I call suggestion there are two "if" snippets like below.

How Can I edit/remove built-in suggestion(first "if" snippet)?
