Currently this is not possible and has been noted as a feature requests.
I actually just did this. What I did was create a specific user in Orion, we'll call it "AVAIL". I then created a specific view for that user and used it as the summary Home page. On the page, I referenced each report in an individual resource (i.e. Resource Column 1 has report#1 then report#2)
Then I set up report sceduler to reference that user's root summary view Home page and used the AVAIL user's credentials for login. Worked for me...hope it helps you out.
