More options when flagging for migration

When I select Off topic option in Vote to close it shows only few options. I know that this question belong to Android Stack Exchange.

How can I select that option to tell the OP to ask there?

The close window shows the below options:

• Meta Stack Overflow
• Server Fault
• Super User
• Tex Stack Exchange
• DBA Stack Exchange

How to add other option?

Answer 1

You don't. Close it as off-topic & then Flag -> It needs Moderator attention -> Mention where it should be migrated
