Create a macro to fill empty cell with product above

Hi, I hope you are well.

I have been trying to solve for quite a while and hoping i could leverage some knowledge on here!

We have a sheet that provides us with lines of products. If the customer ads 5 of the same product throughout the year. There will be 5 lines of code however on the first line has the product name. (see image attached for an example)

I need a loop that will copy down the product name until another product is met. Once another product is met I need it to call the loop again all the way down the sheet so each line has a product name associated with it. (Could be 20 plus products but for this example I have only included 2).

All help appreciated I cant seem to figure this out!!

Thanks
AM
