Create an option to include TODAY in the LAST Filter Range Type

What is the problem or goal the end user is trying to solve or accomplish?

When using the LAST range type, the syntax is actually used < rather than ≤, which means today is not included in the query.
However, the End field is always exclusive for all the temporal filter types.

How are they solving it currently?

Use the ADVANCED range type, and enter for example Last week on the Start field. Leave the End field blank.

What is the recommended solution by the Customer?

Create an option to Include TODAY on the LAST range type. y ≤ x ≤ z
