Currently, when you have a Master Layout in your screen and the have data entry enable in either the master dataview or a slave dataview, you will only keep the Master Layout selection if you use a default "Save data entry".
If any procedure is required to do some calculation and therefor you need to refresh some calculated cube in the screen, the "Refresh screen" step will make you loose the master layout selection.
My idea is to add a way to keep the current Master Layout selection either by adding a new option or new step to force to keep it, or for trigger on dataview not to reset the selection on refresh.
