Specifying UDT Parameter as a String instead of Numeric

I’ve run across an interesting situation where I need to be able to instance a UDT with a parameter like 0883 and have it stay as that value (it is a string, despite it “feeling” numeric). Within the Designer UI, anything I try changes the parameter value to 883, making the assumption it is a number. Does anyone know of a way to force a parameter to be a string value outside of performing an import via json/xml? (which does work btw, so I’m not exactly stuck, just wanting an intuitive way for maintenance of the system to be done via the designer when new objects are created)
