Can I create a

Hi.

New to SD+, but want to set it up to automate a few processes - the main ones are onboarding and offboarding.  I'm creating my own service template for onboarding and have a couple of things I want to put in place.
  1. I have a Employee Start Date custom field.  I want the earliest starting date to be a minimum of 10 working days from when the request is raised (=today + 14). 
  2. I have another custom field called Employee Line Manager.  I want this to be a drop down of employees that has their name and email address.  I hope to be using the email address to get the line manager to complete the resource info part of the request.
What would be the best way to achieve these if at all possible?

Cheers
Tony
