Filtering in zip-codes



I would like to be able to filter out only zip codes starting with a certain number not containing the number. As it is today in SC15 I will get all zip codes containing that number anywhere in the zip code.



I would like to see visits and sales from all zip codes starting with 16 ***.

However filtering "16*" will give me all zip codes containing 16, such as 12316 and 91620.

This makes it impossible to get data for only some specific zip code areas.
