Assets - Computers - Volumes Free Percentage - change datatype from string to int/dropdown

Hi.
It would by really nice to have value: Assets - Computers - Volumes Free Percentage
as int/dropdown (like Characteristics - Last Inventory Date -- "-1 months" in Dropdown).

For using Saved search "show me assets with <= 10 % free disk space" we must construct such huge query:

(from 100 to 11)

Because there is only: contains, not contains, is empty.

Please, implement Volumes Free Percentage as int/dropdown or enable compare operator "between values", "less than", "more than". Thx
