Macro for copying data from one workbook to another under certain conditions, and a button

I have two workbooks, Workbook A and Workbook B. Workbook A has data that I need to input into a specific worksheet (let's call it "Data") in Workbook B. The data I need from Workbook A is in A18:AM18. I need it copied into Workbook B in the "Data" worksheet. However I need to do this each month, and the location where the data needs to go changes because it is updated each month. I would like to post the data to the first empty row starting at D and going to AP. In the same row, I would like to input "APAC" into column C, and pull down the existing formulas from the cells above in columns A and B. I also need this to be created into a button so I can just push it each month and the report updates.

Thank you very much for your help in advance!
