Access a cell by name using the `spreadsheet` gem

If I have a sheet variable that is of type Spreadsheet::Excel::Worksheet, right now we access B2 by doing:

MY_CUSTOM_CELL = [1, 1]
sheet[*MY_CUSTOM_CELL] # => Contents of B2

In LibreOffice (And I'm sure Excel), I can assign a name for that cell in the "Name Box". See the image below, I've given B2 a name of "CUSTOM_NAME".

Instead of accessing the contents of that cell using the row/column coordinates, is it possible to access it via the name? This would make it easier to adapt to future change if the cell changes location. I'd like to do something like:

sheet.find("CUSTOM_NAME") # => Contents of B2

I was looking at the documentation found here but was unable to find what I was looking for.

If the gem doesn't allow it already, how would I go about implementing it myself?

Although the other answer may be a good alternative (I have not personally unverified), the answer to this question is no.

Spreadsheet Issue - Feature - Retrieve a cell by its name, not just row and column

There currently is no way to retrieve a cell by its name using the spreadsheet gem.
