City "Purchasable" Events

[Drakhem]

I know how much I love the atmosphere of Bedrock with all the care taken to put in place the ATAT's and Troops that really turn the town into something special.

Checking out the items we can purchase off the NPC it the Hotels the list is really fantastic and I've been putting down some of my own (shot down Tie Fighters and destroyed ATAT's of course being rebel!).

My question is, once purchased, the items have a duration which starts ticking from the time of purchase. As the goods come as a deed is it possible to have the timer for them start when the item is actually placed? This will allow the option to purchase a stock of the deeds and will make it much easier to pop them down and add some real atmosphere in player cities without being a real pain to do.
The other option would be to have the items permanent and come off the city maintenance?

Just thought Id flag it and get others thoughts
