Hi @brainer ,
I raised this a while ago, custom mode gives you this control but when changing dates causes it to go wrong. We can see the vision of Phocas when looking at Financial statements as this does provide more date controls like your request. It works well there due to the strict column structure of P&L’s. It becomes a minefield when using a standard DB such as Sales or supply chain as they are all different. I did raise this here as a means of controlling data better: Parent & Child Period Ranges - Current Month Issue - #7 by jimmueller
Very wordy, but basically if we could introduce variables into dashboards we can use customer to offset each column based off a single date which would fit in your request. Also this would then open up what-if scenario dashboards (what if there is a 5% increase in sales).
