Excel Macro Enhancement Needed

I already have a working Excel workbook with VBA macros, but I need the core code refreshed rather than rebuilt. The goal is to modify the existing functionality by revising the current macro code and layering in a couple of new features that will streamline my workflow.

The file is clean and well-organized, yet a few routines have grown outdated. I will share the workbook, walk you through its current logic, and outline the new feature set I have in mind so you can see exactly where the alterations belong. Most of the work will involve updating the VBA modules, testing everything against sample data, and ensuring the new additions run seamlessly with the old logic—no broken references or performance regressions.

Deliverables:
• Updated workbook with revised VBA code
• New features integrated and fully tested
• In-code comments explaining changes
• A short change log so I can track what was done

If you are comfortable digging into existing VBA, optimising what is there, and bolting on new capabilities without disturbing what already works, I’d love to get started right away.
