How to get a WPF slider with three fingers

Question

I want to use a slider control that has 3 thumbs - they don’t have to cross each other, but the user should be able to independently move any thumbs.

Reference Information. I created a trading application that requires input:

1.set of production start date

2. end date of a set or date of a set of tests (they are identical)

Installation end date 3.test

I did this using 3 slider controls located one below the other, but this is confusing. Instead, I hope to use one control, if possible.
