WaterCAD MSX with User Data Extensions

Hi Everyone!

I try to run a Multiple Species Analysis on a large (30.000 pipes) model.

I have 2 additional properites (parameter) for every single pipe.

I tried to initialize the parameters in the Model Configuration text input, but that box is limited in row numbers.... it can only contain ~1290 rows. Unfortunately, I have to add these parameters as a function of the material and wall thickness of the pipes, so i cannot use a default value...

I tried to find a workaround by adding user data extensions of the same name, and imported the values of the parameters pipe by pipe, but it seems like it has no effect.

The manual said (i was afraid of this...)

Note: The user data does not affect the hydraulic model calculations. However, their behavior concerning
capabilities like editing, annotating, sorting and database connections is identical to any of the standard predefined
attributes.

Do you know any workaround for this limitation?
