Multiple Default Select in Drop Down

Is there a way to have multiple default drop down selections on a drop down list with multi select enabled?

It seems that only one selection is available as a default.

Thank you!

I just figured it out (after finally posting).

For fellow newbies:

Double click on the blue circled drop down while in edit mode and add "default=" in front of all default answers. My test case follows:

{formmenu: breathlessness; default=headache; default=nosebleeds; fatigue/confusion; tinnitus; vomiting; profuse; blurred vision; multiple=yes}

By the way the multiple select is not represented in the formmenu but it works just fine in practice
