Allegro: Select Pin and change Properties

[hikom]

Hi,

i'm learning the usage of allegro and concept hdl and have some
problems with the user interface.
i want to create a package symbol. therefore i choosed the library
flow in the project manager and started allegro symbol editor. after
this i choosed new and selected package symbol (no wizard). so my
problem is, when i placed a pin with a certain padstack and pressed
done, how can i select another pin to e.g. change the position or
padstack???
thanks in advance.

greetings,
hikom
