Can we change position of drop list position created by signal?

Hello,

Suppose a droplist was created by following:

{
  "$schema": "https://vega.github.io/schema/vega/v4.json",
  "signals": [
    {
      "name": "selected_team",
      "value": "",
      "bind": {
        "input": "select",
        "options": ["Team1", "Team2", "Team3"],
        "name": "Select Team: "
      }
    }
  ]
}

And it's position is on left bottom corner. Is there any way to move it to center or top left corner?

Thanks.
