CAD model DimBounds stored as nominal vs middle

Guten Tag,

does anyone tried to force Windchill create STEP representation converted to middle dimbounds?

According to our norms/rules we use nominal dim tolerances like 10,5+0,2 and in that way it is saved in Creo and WCH. Then STEP representation in WCH is always created from this default model value 10,5 as nominal.

When our suppliers asking for STEP converted to middle bounds (dim is changed to 10,6±0,1) we have to open Creo, convert model to middle and store it as STEP manually which is pain.

Is there a way how WCH user can generate STEP without opening Creo and converting CAD from nominal to middle manually?
