Automating append table after importing new monthly files

Hi,

For a report i use monthly files that I import, and then I  "append" these tables together so that I have one big table that contains all data for several months, like costs, budget, etc.

Is there a way that I can append this table automatically with the new monthly file after import so that i have no or less manual actions to take after import? So basically adding a new file each month to the append table.

Im not even sure if there is a way to automate actions / steps in powerbi desktop.
