Typeahead as an Option to Dropdown Lists and Checkboxes

Currently a Typehead field must be connected to a "Referenced Object Type" which includes Company, Group, Job Role, Portfolio, Program, Project, Team, Template and User. While this is very helpful, the current Typeahead feature is limited in functionality and misses important option.

Users should be able to connect the Typeahead fields to a list of values as an option to Checkboxes and Dropdowns allowing a single or multiple value selection. Example: We have a list of approximately 250 aircraft a user should be able to select from. Scrolling through a Dropdown list of 250 values is not practical. 250 Checkboxes is not a good option either.

Short of having this option, we are using a Single Line Text Field for the user to enter the aircraft number which leads to inconsistent data entries. Please help !!!
