Can 'Type Ahead' or Search Suggestions be turned on/off depending on module or picklist?

Summary:

Are we able to turn 'Type Ahead' on/off per pick list, per module, or is it at instance level?

Is it possible, if turned off or adjusted, that the cache of recently selected values could appear at the top of the list? This would be the ideal scenario for a number of pick lists (but not all).

Examples of what this may look like:

• If I was looking in the HCM module to add a competency to my profile, I would not be interested in a competency that I had previously selected. I would, instead want to scroll the entire list of available skills to make my next selection.
