Proposed Feature

I want to be able to select the warehouse from which I am going to assemble freight from the assemble freight window.

Motivation

If I have a project with multiple warehouses I can click the dropdown box to select one of them and then click assemble freight to assemble freight for a specific warehouse. BUT, if I leave the dropdown as All warehouses and then click assemble freight, I only have the ability to assemble freight for the first one on the list.

I don't have a way to switch between them from this screen, I have to go back to the project.

Suggested Implementation

From the assemble freight window, I should be able to select which warehouse I am looking at without having to go back to the project screen.

I recognize this isn't a high priority because there is a work around, but I thought I would get it written up so its on a list for consideration somewhere. This would just be a minor quality of life improvement.

This is good and easy UI improvement. We can have dropdown as you suggested which lists all available warehouses and implementation wise its just redirect to another page .../warehouse/<warehouse-name>/create-freight
