Clearing Competitions that have been entered

[Golden Lotus Stables]

I was wondering if there was any way to have the competitions that have already been entered, get cleared and not show up.Im getting a little annoyed when ever I click on a competition and it says "This handler is already entered and may only be entered once". So if one of our horses already entered it, why is it still showing up. Anyway that can been looked at been rectified. I noticed certain competitions allow multi entries from the same player others not and give that error message, so ones that do not allow multi entries should temporarily be cleared and pop up the next day or until competition runs.

Thanks
