Does OFSC support the "LEFT/RIGHT" functions in visibility conditions?

Summary: We need a visibility condition based on the last character of a string.

Content (required): Lets say for example we want to display a text message when a user installs a part number that ends with the letter "H". Visibility conditions in OFSC do not have 'Starts with' or 'Ends with' so I tried using the formula option instead and wrote a formula with the 'RIGHT' function, but OFSC gives a validation error "The function "RIGHT" does not exist". Does anyone know a way to achieve the equivalent of the 'RIGHT' function?
