Ability to not have Web Maps accessible in Collector for ArcGIS

Idea created by philip_marley@fws.gov_fws on Dec 11, 2017

    When using ArcCollector, a user could have many many maps showing.  Many of these maps will possible never be used.  They are just cluttering the interface.  I would like an option in AGOL/Portal to turn off the ability that the web map will be accessible via Collector.  This will allow the user to have some control over how data is collected.  The user may only want people editing data via Web App and not Collector, but if you have an editable data layer, then the map shows in Collector.  Need a way to prevent this.
