Cascade select

Dear All,
I want to use cascade select, but in the “filter_country” column, I want to combine or list more than one filtering digits for country. I want “Other” to appear if any of the countries is selected. I have tried 1-3, 1 and 2 and 3 … and other options but it couldn’t work, Any help? @Kal_Lam and everyone? Refer to the table below

list name name label filter_country
country 1 Brazil
country 2 Congo
country 3 Malawi

code 1 +55 1
code 2 +66 2
code 3 +265 3
code 88 other 1 and 2 and 3
