Interactive Brokers Market on Close Order

I use Interactive Brokers and I send out up to 20 limit buy orders each day. If any of the buy orders get triggered, I would like the position to be sold as a market on close order at the end of the day. Is there a way to set up a bracket order or something like that where I could place my buy limit order and market on close order at the same time?

 

In TWS, right click on the order and select Attach -> Limit, then change the LMT type with MOC.

 

That works perfectly, thanks so much!
