Copying Price Layers

This is perhaps a feature request, but I wanted to float the question of whether there is a way to accomplish what I want to do.

Basically, when I add a price layer to a performance, I want to begin with an exact copy of one of the already existing price layers.  Then I'll change prices and start/end dates.  But things like default gl codes, specific price type gl codes, default/specific designations, default ticket design seem like they should stay the same 90% of the time.

The specific thing I'm trying to accomplish is to create a layer for each performance (called "Day of Show") which adds a specific amount to each price, say $2, starting on the day of the performance.  I don't want to have to dig through our long lists of gl codes, designations, ticket designs, etc when setting up the layer.  Ideally I'd want to be able to have a one button "copy" that would just create a duplicate of the current layer, just asking for a new layer type.  Or it would be nice if, when creating a new layer, the defaults were set to whatever the previously created layer for that performance was.

But is there a way to get this to happen, or something close to it, using the currently available tools?

Thanks,
