If you wish to generate an HSA contribution plan to make tax-exempt contributions to HSAs, you would select "Health Savings Account (HSA) Contributions" as a type of benefit offered. (The employer would be listed as the administrator of the PCP for HSA contribution purposes.) A Premium Conversion and Health Savings Account Contribution Plan SPD and Plan Document will then automatically generate.
Please note that Premium Conversion and HSA Contribution Plans do not have to be included in the Wrap Documents, as they are not ERISA-covered, but some brokers choose to include them in the Wrap to keep all the benefits together in one Welfare Benefit Plan. While it would be prudent to inform employees about the benefit in some manner, determining which non-ERISA benefits to include in the Wrap is ultimately at the employer's discretion.
