In HubSpot can we use one Custom Field across multiple forms - with each form using a different set of field options?

A custom property is a property that you create to meet your unique needs

Adding new options to a custom field will add them to every form that the custom field is used. 
    • This requires the manual updating of every form after new options are added. 
    • There's a work-around involving creating new custom fields for each form with options that wouldn't change and specific labels.
