Seeking Help with Dynamic Granularity and Last Value Integration

Hello everyone,

I'm currently facing a challenge in Cube.js and would greatly appreciate your insights. Here's a brief overview of the issue:

**Issue Overview**:
I am working on integrating a Cube.js query measure that depends on the last value of a numeric column within a dynamic time slot. The granularity of the time slot is dynamic, meaning it is chosen by the frontend.

**Objective**:
I am trying to retrieve the last value within the chosen dynamic granularity.

_Database Dialect:_
I am using PostgreSQL.
