I need help connecting each of the records in Block M, which I'm breaking the txt. I want the outputs to come out in the same Excel, separated by sheets.In this way:

I'm using these respective paths: %User.MAIN_DIR%\Bloco M.xlsx|||M001, %User.MAIN_DIR%\Bloco M.xlsx|||M010, %User.MAIN_DIR%\Bloco M.xlsx|||M030.
When I put it running the way it is, it gives me this error: "the process cannot access the file because it is being used by another process".Which indicates that the outputs are using the same excel created at the time of the flow run.
Please, I need help.
