Not sure if this would work or not, but I was considering in the case of a layer which requires a longer build time, that I would use a larger container. The idea being that a bigger container would take a longer time to fill giving the time required to draw a time intensive layer, granted this would increase the overall build time and the amount of resin required but I thought it was a simple solution. Other then this as the others have mentioned here I was gonna have a go at controlling the drip rate to speed up or slow down the transition between layers.
