Always one specific value is selected in the list box along with the other selections

[#1]

How can I have one value always selected in the list box.

In the below tables, when I make any selection in the Region, I want APAC to be selected along with my selections. Similarly when I make any selection, in Market Sector, I should have the FI selected along with the selections I want.  When I don't select anything from the Region or Market Sector, then it should not select anything. Thanks for the help.

Region
North America
APAC
EMEA
LATAM

Market Sector
FI
ABC
SF

You need this action:

='(' & Chr(34) &'APAC' & Chr(34) & '|' & If(GetSelectedCount(Region) >0, Concat(Chr(34) & Region & Chr(34), '|') & ')', ')')
