No probs!
My first time around with SO I did it all from the TWS tabs with generic combos but this time I've become fond of option trader. Its much quicker to bang out combos than the generic combo builder (ie. it adds a buy/sell depending on whether you click bid/ask rather than just alternating buy/sell like in generic combos). Plus I recently discovered that you can have multiple tabs in option trader (up the toop Option Chains>Add Tab) which makes managing multiple entries at the same time easier.
