Is there a way to read Excel attributes(columns) dynamically?

I have read multiple questions\\answers\\commentaries around this topic and I may be more confused than before.

Here is the scenario:

1. I have an excel workbook
2. The sheet names are always the same
3. Some of the columns are static
4. Some of the column names change-- and sometimes there are more or less columns
5. I need to capture the column names and row values then process the info
6. The only way I have seen to update columns is to manually refresh the reader with 'Update Feature Types'
7. Is there a way to dynamically read in new or changed excel column names without manual intervention? FME 2021.2

Thanks!
