I read that Knowledge-base article before posting. It states that you CAN enter FIFO -- but not HOW to do it. Also, I have been using the trial version to test functionality for several days. I have all my investment transactions loaded. This is where I am having problems finding HOW to specify FIFO. This is the key feature I'm looking for, so it is kind of important to me :)
Open Moneydance to your investment account.
Click the 'Securities Detail' tab.
Select the security in question from the drop-down list in the upper, right-hand quadrant.
Click the 'Edit Security' button.
In the resulting form, select the 'Lot Matching' radio button.
