Multi-select Typeahead field for custom forms

Description - We currently are using typeahead fields for single select employee lists on a custom form for Marketing and have a need to have an employee list with a multi-select option

Why is this feature important to you - Since employee data lives in Workfront, it makes sense to be able to choose the appropriate information from Workfront instead of having to point to an external resource

How would you like the feature to work - Would like the Typeahead field to be able to have both a single select and multi-select option

Current Behaviour - Typeahead field only allows a single select option
