Export Groups to Excel

I have done a little testing

I added some group names to the Notes field with a carriage return before and after each

I tried running the bibliography report

The result is not what I had hoped.  I do get a group name with a number, but the publications are listed under each group, I don’t want to list any publications in this type of report

Result

<groupname> (number in group)

each publication

each publication

each publication

each publication

<groupname> (number in group)

each publication

each publication

each publication

each publication

<groupname> (number in group)

each publication

each publication

each publication

each publication

What I would like

<groupname> <groupname> <groupname>
numberingroup numberingroup numberingroup

Is that possible? Basically can I suppress the publications from printing, and further can I change it from vertical to horizontal?

By editing the output style I can get the output to look like this:

2013 collab    (419)

2013 collab 02 - all    (60)

2013 collab 02 - inter    (9)

2013 collab 03 - all    (75)

2013 collab 03 - inter    (14)

2013 collab 03 - intra    (8)

2013 collab 05 - all    (150)

2013 collab 05 - inter    (34)

2013 collab 05 - intra    (19)

2013 collab 06 - all    (125)

2013 collab 06 - inter    (22)

2013 collab 06 - intra    (19)

2013 collab 07 - all    (67)

2013 collab 07 - inter    (14)

2013 collab 07 - intra    (3)

2018 collab 02 - inter    (6)

2018 coolab 02 - intra    (4)

But I haven’t figured out a way to get it going horizontal yet.
