Split in microflow with 3 posible string values

I made a web service in a third party application and with Mendix, I can consume some variables. One of the variables is a string with A, B and C as possible values. Now I want to make a split in my Microflow, but that's only possible with an enmumeration or boolean. How can I make a split with the three values of the string?

Use a split with $variable = 'A' as the argument - which will then evaluate as true or false. Follow with additional splits for the values B and C
