Is your feature request related to a problem? Please describe.
Describe the use-case and give concrete real-world examples
I want to detect changes on pages that are only reachable after filling a form and submitting it (browser steps), which results in a post request showing a result based on the input:

https://example.com/ -> Fill form with value 1 & POST submit -> https://example.com/result shows the desired result
https://example.com/ -> Fill form with value 2 & POST submit -> https://example.com/result shows the desired result

The unique constraint on the URL prohibits that there can be 2 checks implemented with the same start URL.

Note: I tried adding a parameter and anchor to the URL (https://example.com/?foo && https://example.com/#foo) but the URL handling of the website is smart and does not show the input form in this case.

Describe the solution you'd like
The unique constraint of the URL must be lifted so multiple change detections can be created where browser steps need to start on the same URL.

Note: This feature request conflicts with the following feature request: #1571

heya, yeah actually I agree, this constraint is really not necessary - or maybe could be a config option
