Import selected items from INI without overwrite

Dear colleagues,

I exported a configuration to INI-file and wont to import selected items from it to another WinSCP installation, but without overwrite all existing items.
How do I accomplish this?

If it is not possible, then it would a nice feature of the WinSCP.

Thank you very much.

I assume that by "items" you mean "stored sites".

Export your configuration of the "another WinSCP installation" too and copy over all [Sessions\*] sections from one INI file to the other. Them import back.
