Auto Retrieve New Symbols (EOD Data)

How can I auto retrieve new symbols in each day (EOD Data)

Once I've already finished set database (Metastock data plugin) and "Retrieve Symbols"
For example. the day I've retrieve symbol have 4 symbols that is AAA,BBB,CCC & DDD, then today have one more symbol is ABA. So the problem is in my metastock data have this symbols (ABA), But amibroker will not include this symbol in Database. Until I've click file > database setting > configure > retrieve symbol again then this symbol will include in database.

So does it have any solution to solve not to manually "Retrieve Symbol" all days?
Thank you.
