If the dropdown allows more than one selection, then the system will automatically add an option to select or deselect all. I would like the select or deselect all option to be optional

Description -

Why is this feature important to you - We want the ability to control whether the select all option appears in a mutifield dropdown or checklist. 

How would you like the feature to work - Add an option in the custom field that allows the admin to instruct WF to add the Select All option.  If not selected, then do not allow the ability for the user to select every option. 

Current Behaviour - Workfront adds the Select All/ Deselect all option automatically.
