Clicking Account in quote does not autofill custom fields

Clicking Account in quote does not autofill custom fields

Hi,

When clicking the Account option in Quote only the Billing/shipping address details are automatically populated and not any custom fields we have created. I have been looking for a mapping option when creating a quote but cannot find it anywhere, does this exist? Similar to setting up the Lead field mapping I would like to map fields from the Account to be automatically filled in the quote form.

Any help will be very appreciated.
