I am doing a quality analysis for which I have created specific trends. Now whenever there is a new quality issue, I can use these trends to analyse the problem. However, since the issues occur on different times and dates I need to change the basis layer and the reference layer for correct comparison. 

I created a dashboard with all the relevant information. The information is very simple. It shows multiple graphs of KPIs with a basis layer and a further reference layer for comparison. To save me some time, I was hoping that it is somehow possible to change the date and time of both layers for all of the trends at the same time. Is this possible and if yes, how?
