I know that I can create a custom link or button on accounts for example that will pass the account id to a report.

ex.  button link would be something like :  /00O80000003PXuG?pv0={!Account.Id}

I have a custom object with a lookup field to accounts.  Is there a way to build this same type of functionality to pass the account id chosen in the lookup field to the report?  I don't want to pass the custom object id, but the id of a lookup object.  Can that be done?
