Need more than 1 performer on one checklist template

Hello team,

My requirement is that I need 2 performers on one checklist template's tasks. It means it has to be triggered to the user and once user attach the documents in the same Checklist, then the same can be sent to the candidates as well.

I tried to do this but not able to find any option.

Requirement-

Client wants that a user will upload the VISA Document in the checklist task and then the same can be sent to the candidate for candidate's VISA details.

Awaiting response.

Thank you,

Latika
