When creating a new custom field for tickets, when using the "dropdown" type of field, be able to choose multipe options. We want to use this for onboarding and a list of systems the new user needs access to. Right now you can only choose one option. We would like it to be:

Title: Systems Needed:
And then be ablel to choose multipe items under that title. Users could choose all the systems they need to have access to.
