Display account field within sales quote header

Hi all,

I created a new extesion field in account, and would like to have it also in sales quote.

I know I can extend it with extension scenarios, but i want to have the extact same field in sales quote, so if I change the field at the account, the change will be reflected to all sales quote of that account.

using workflow isn't an option since the update can only happen after the sales quote was modifyed, and i need it to be reflected even without any modification was made to the quote.

any ideas?

Thaks,

Dror
