Thank you for your reply,
However, let me clarify my situation.
- group 1 is A4-A12 (the header name of multiple rows, and B4-B12 will be the column to insert ID of participants.
- I'd like to add one more participant to the group1, which will be at B13, which is now the first column of Group2.
- I'd like NVDA to say "group 1 A4 through A13" instead of "A4 through A12".
