I JUST NEED HELP I AM NOT SURE WHAT TO DO

Hello Everyone :)

I have this scenario, I currently making a very huge family tree.. I tried to make the name and years of a person put inside a box.. after thousands of boxes made, I then realized that the boxes are too large that would take so much spaces when constructed in a family tree.. I then tried to group per box just only few (because what I usually do is just duplicating boxes by selecting the box and the texts inside without having to group them and just edit the texts inside the box for another person)  and tried to use the attributes eyedropper to set new sizes for the rest of the boxes but before that, I set one new resized sample box proportionally (which has texts inside grouped together). The result is only the box changed not as a whole group. I tried checking everything on the transformation flyout but still the same. How can I change the rest of the boxes by not manually entering the height and width sizes each box?? it would take me hundreds of hours to finish it all.

PLEASE HELP :(

KIND WISHES,

Lauren :)
