It would be a rare situation where you were forced to go early unless perhaps you were last in your category. When you bid for training you specify if you want to go that month and then put in the dates you would like. If you don't want to go you tell the computer you don't want training in that month and then put in some what if choices in case you are forced to go. So far I have always had training in the month I wanted and near the dates I want.
