use @SelectionFields in cap cds annotation to define more than one filtre

[JAK]

Hello,

I create used the annotation @SelectionFields to specify filters fields for my entity. 
Then I need, and for the same entity, to create an other selection fields list, but it is not possible. 
My idea is to specify a qualifier that I can refer to it in the definition of smartFilterBar to display the new list of selection fields. 

any one can provide an example to implement this logic or propose an other idea ?

Thanks in advance.
