[dba-SQLServer] Create table within schema

Using SSMS, how does one create a table within a schema? (It's simple
enough without the GUI, but when I use the GUI, even if I name a table,
say, Arthur.MyTable, once I save it, it's called dbo.Arthur.MyTable. Is
there a way within the GUI to specify the schema to use first and then
create its tables?
