Freeze Pane and Split Worksheet

I've built a spreadsheet to track time spent at a client's office (with previous help from the forum), and have one final thing I would like to do to clean it up and make it more presentable.

I would like to split the worksheet and freeze the top few rows. However, I'm coming across a couple of hangups.

First, it doesn't seem like I can do both at the same time.

Second, I don't want the split just to keep the different sections scrolling horizontally independent of each other, I want them to scroll vertically independent of each other.

My spreadsheet has the entries for time in a table on the left side, and a summary by category in a smaller table on the right side. What I would really like to see is the headings across the top to be frozen (either across the whole worksheet or just the table on the left), and the entire table on the right to move completely independent of the other table, that way I can always see the summary to keep track of time better.

Thanks in advance! I appreciate any advice given.
