DATAX针对ZIP的压缩包如何选择里面的部分文件

我的一个FTP日期路径下面有两个ZIP压缩包，每个压缩包有两个csv文件，我的ftpreader，如何读取每个压缩包里面的一个文件来，写到其他地方去（因为压缩包里面的两个文件格式表头不一致）

Start with the ftpreader configuration and reproduce the described FTP date path containing two ZIP archives, each with two CSV files whose headers differ. Determine whether one CSV can be selected from each archive and written to another destination; the issue names no source files or tests, so the relevant entry point and verification steps still need to be located.
