We have properties in String type in a dataset, and these properties contain more than 2 values, and this won't affect the import to the Analytics server.

For example:

Property Name: CoolDownType

Value: Water; Air; Oil etc.

What's your dataset look like?

We have explored your suggestion and we found the following observation.

Data upload is possible for multiclass with Option(a) : String & categorical & Option (b): String & continuous
Model building is possible with only option(b)
Here problem is ThingWorx analytics converts the Classification problem to regression problem.
Sample dataset is given below (Few rows are mentioned )

#	Speed	Flow	Head	torque	faults
1	2707.4	14.778	44.66	16.045	broken_blade
2	2965.6	33.591	16.438	7.5257	cavitation
3	2874.8	39.92	9.7401	10.019	healthy

If you have the TWA Extension Package with you, and you'll be able to find the sample dataset like BeanPro and Parking. The expected goal field for these 2 datasets are Numeric type, and we can use the Categorical properties as dependencies for prediction.
