GC Transactions Cleanup

Hi All,

Sorry if this has been covered previously.

Is there a simple way to cleanup transactions to remove items that you no longer need.

I find that I tend to test out things and then before I know it I have a full transaction list with items that I created then deleted or moved around etc.

I thought there might be a way of flattening the transactions to the once needed? maybe wishful thinking. 

One thought is a Generated Node? Does this take any other information other than what is needed?

Thanks

Wayne
