Changing Default Symbol Pin Type

Hi,

When creating a new pin for a symbol (Symbol: Create -> Pin...), there's an option to select different pin types:

I find the type "block" particularly useful, as it shows the direction of the signal (input, output, and so on). Also I like to directly place the pins on the green boundary of the symbol, rather than with wire stubs. So, for example, a pin with the default style compared to my desired style looks as follows:

How can I modify the Virtuoso environment to make the desired pin style to be used when creating a new symbol (Schematic: Create -> Cellview -> From Cellview)?

I'm currently working with Virtuoso IC6.1.8-64b.500.29, in the legacy "L" modes.

Thanks very much for your response.
