使用bytes.replace时是否可以使用通配符?

I am programming in Go and I read a text file in and I replace multiple things on it to translate the code from one language to Go to be able to run. The problem I am having is that when trying to replace things like Println statements I cannot get a parenthesis on the end of the statement without being really specific to the code I am converting. Is there a way to use the code like this?

src = bytes.Replace(src, []byte("Insert"), []byte("Println(" * ")"), -1)

and have the ability to just put a parenthesis at the end of the line of code?

    package main
    
    import (
            "fmt"
            "regexp"
    )
    
    func main() {
            src := []byte(`
    Write(1, 3, "foo", 3*qux(42));
    WriteLn("Enter bar: ");
    `)
            re := regexp.MustCompile(`Write\((.*)\);`)
            re2 := regexp.MustCompile(`WriteLn\((.*)\);`)
            src = re.ReplaceAll(src, []byte(`Print($1)`))
            src = re2.ReplaceAll(src, []byte(`PrintLn($1)`))
            fmt.Printf("%s", src)
    }
    

    (Alse here)


    Output:

    Print(1, 3, "foo", 3*qux(42))
    PrintLn("Enter bar: ")
