Filter showing always 1 default value + other(s) when selected

[GAstarting]

Hello everyone - I'm new here, so I hope someone can help

I have a filter with 5 items (Milestone, Task, Task_Cty, Subtask, Subtask_Cty)

I would like to display a table linked to this filter as

if Milestone is slected - showing Milestone

if Other any other (Task, Task_Cty, Subtask, Subtask_Cty) - can be multiple - Showing Milestone (by defalut) + other(s) selected

'til now, found only the possibilty to display by default (if not filter a value) but not what I'm looking for

Thanks a lot in advance for your help

@GAstarting , Assume these value are coming independent dim , and you have measure = measure 

Var _sel = countx(allselected(dim[Value]),[Value])

var _cnt =countx(filter(allselected(dim[Value]), [Value] ="Milestone ") ,[Value]) 

return

if(isblank(_cnt) , [Measure] *_sel , [Measure])

If this does not help
Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.
