I've made an Access database and have used it with Word to create letters through letter mailing wizard.

However, my boss wants me to simplify this even further

He would like this - a button of sorts so when he clicks on it a Word file is automatically created and a template is filled with data from highlighted/selected row.

Is this possible through some unbelievably cunning use of macros or I am doomed to eternal process of explaining just how exactly of letter mailing wizard works?
