Currently, there's no way for an element (i.e. a Kanban element) to be connected to multiple filter elements.
This would be useful for example if a user needs to create an interface with multiple sections. The interface having a main general filter affecting all the elements in each section, and each section containing secondary particular filter elements.
The connection here would be "AND" between the filter elements.
How does is solve the user problems?
This would allow making the interface much simpler, instead of repeating the same filter elements over and over again across all the filter elements of the page, a general filter would be set at the beginning of the interface and the following optional/secondary filters would be left for each section across the interface.
Currently the interfaces with this approach are super repetitive and a user needs to apply a single filter multiple times.
