What inspired this wish list request? The search bar in the Data Filter clears any previous selections. This makes multiple selections from long lists of many levels really tedious; you have to scroll through the entire list to make your selections.
What is the improvement you would like to see? The search bar in the Data Filter should not clear your previous selections.
Why is this idea important? This feature would enable easy & fast multiple selections from long lists. I'd like to use it to select ingredients from a standardized list of all of our raw materials that would feed a DOE factors table. This way, scientists are all using the same names/identifiers for ingredients in their DOEs. Without this feature, I'd have to build a bespoke tool & JSL scripts to do this.
