Table that stores the information of all custom table in ECC which are maintained by SM30

Hi All

Good Afternoon.

Is there any such table in SAP that stores all the custom table names which are maintained by SM30 transaction.

Actually my requirement is to segregate the table that are maintained through SM30 and those which are maintained directly.

I have a list of table that contains more than 1000 custom tables.

Or is there any other manner i can find the tables names rather than going one by one to find that particular table is maintained via SM30 or not.

Thanks in Advance
