Copy data from broken list in a column to a row

Hello all

I'm a total novice at macros and I'm currently working on creating a more efficient reporting process for my team. I work for a bank and am responsible for managing operational risk and processing on options trades.

I have a report where trade details and each trades portfolio number is listed in rows. Each portfolio might have one or more trades and some days we might have some portfolios that might not be there other days. Basically, I need a code that can go down the column to the end of the data and copy the different portfolio numbers into a specified row where a formula under that row will count how many times that number is repeated in that column. Please refer to attached for an idea of what I'm looking for and thanks in advance for your help.
