Account order in iOS app

When processing mail in the iOS app it seems to have long delays in checking the accounts. Outlook.com accounts seem to get processed immediately and then there are long delays before emails from other imap accounts come in. Is there any way to define what order accounts are processed in?

Sorry if this is the wrong place to ask about the iOS beta app.
