While being able to use the Multi-Select field is very useful, it would be really great if there was a way to compartmentalize additional options. For example:
Multi-Select Option 1
> Sub-Option 1
> Sub-Option 2
> Sub-Option 3
Multi-Select Option 2
> Sub-Option 1
> Sub-Option 2
Multi-Select Option 3
Multi-Select Option 4
> Sub-Option 1
> Sub-Option 2
An Asana user would not be required to select a Sub-Option under a parent item, but it would be a great way to organize, for example, a specific product under an umbrella service based upon requests we receive. If a Sub-Option was selected, both it AND the parent item would automatically be included.
