Slur position

[Danny Sosa]

I'm writing a scale pattern using slurs on certain notes with parenthesis  " _ ; ^ ; () " but whenever I try making a slur above the note Lilypond automatically puts it above the beam. Could you guys help me tweak it so it does it only above notehead?

Here is what I'm trying to accomplish:

And here is what happens:

I thought about just living with it that way, but it doesn't really look good when you see the whole measure:

Thanks in advance!
