Scheduler option to ignore availability on polls?

[wcorkill]

We are running into a problem using scheduler.  Many staff want to offer very specific times for a potential meeting, even times that they may currently have a competing appointment.  In these cases they are willing to re-schedule the other meeting if they had enough votes.

Is there an option or way that anyone has found to allow users to have the Polls ignore availability?  I can't see or find an option that would work to make this happen.   

Part two, is there an option to allow a time to be picked if just one of the hosts is available?  It seems to require that ALL hosts are available before it will allow us to pick a time in the poll.
