tie between voice & transpose a to g

[MING TSANG]

(hope this time the email will not be rejected by lilypond-owner}

Hi lily user:

I have a hard time coding cross voice tie.  I end up of spliting the chord into two voices. Please refer to pdf and .ly files. 

1. How can I code so that it will be the same as ~original.png

2. Is it a lily pond feature that will transpose the whole score even there are two or more key signatures?

Thank you for your help.
