The option is available for STAR - just a bit hard to find (hidden under advanced advanced options 🙂 ):

- **Would you like to set output parameters (formatting and filtering)?**: _Yes_
  - **Would you like to set additional output parameters (formatting and filtering)?**: _Yes_
    - **Maximum number of alignments to output a read’s alignment results, plus 1**
