I would like to have a button that, when clicked, will copy the contents of a
specific row and paste it into the next empty row of several subsequent
ranges.

Example:

Range 1: B8:E12
Range 2: B20:E24
Range 3: B32:E36

There is text in B8 and a number in E8.

I would like to click a button that will paste the information in B8 and E8
to the first empty rows in Ranges 2 and 3 (could be B20/E20 of Range 1 and
B34/E34 of Range 2, and so on, depending on which row is empty in each range).
