How to detect a blank range and paste data?

I have a document that I am trying to format so it works as a source for a pivot table.

Currently it has too much data in column A, so my Macro goes through column A to insert cells to adjust data over so it can be properly nested in categories. This creates blank cells where I then want to copy the data above it and paste so everything is labeled correctly on the pivot table. I'd like to paste to the entire range of blank cells in columns A and B, so I don't need to check each cell each time. This spreadsheet is over 5k lines, so it takes ~10 minutes to run currently.

Original Data:

Column corrected data:

Now I copy the AWD cell to the one below it, next to Grant, and delete the original line. since I don't care about the AWD total row.

I can have anywhere from 2 - 10+ Obj rows here, so I'd rather paste to the entire range instead of line by line as I'm doing now.
