Update value in external workbook when location cell in original workbook changes

In Calc How to automatically keep the referenced cell value in an external workbook updated when the cell referenced, in the original workbook, is moved?

The source workbook has a cell value that changes daily and depending on other updating within the source workbook, the location of that cell changes too. There is an adjacent cell on the same row, with a short description that stays with the cell containing the value.
What is the best way to accomplish this?

Version: 25.8.1.1 (X86_64)

Thanks in advance for any assistance with this.

A standard solution for spreadsheets is a named range.
In the source workbook, add a named range with a reference to the cell containing the total.
In the target workbook, add a formula with a reference to the named range in the source workbook.
