Combining mixture design with continuous factor

[#1]

Hello,

I have the above mixture DoE I want to try out. However, is there any way I can add a continuous factor to the DoE dialog? Essentially, I'm looking for a design that will run this exact same mixture design under two different continuous conditions.

The Custom Designer (DOE > Custom Design) can generate designs that combine mixture and continuous factors. See the on-demand webinar Designing Mixture Experiments (pt. 1, pt. 2) for demonstrations for how to specify the design and analyze the data.
