Grouping

see the attached

when you create groups items are either in a single group and can not be in multiple groups - but you knew that  -

attached is an approach using sets that will will have the look and feel of what you want

it uses superstore data

with Accessories being the target group

next create a parameter to simulate the selection of Group A or B

then this filter - place on the filter shelf and set to TRue

now the viz

when Group A is selected you see this

but for group b yo see this
