System Information
Operating system: Linux-5.5.8-arch1-1-x86_64-with-arch 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 440.64

Blender Version
Broken: version: 2.83 (sub 6), branch: master, commit date: 2020-03-05 21:23, hash: eed1beff88
Worked: (optional)

Short description of error
Every newly created domain uses the same path for the cache. That way, baking any simulation overwrites all other simulations by default.

Expected behavior: Increment the filename by default. - Additionally, when manually changing the path, the input field should turn red if the path already exists.

Exact steps for others to reproduce the error
Create two or more fluid domains and compare the cache path. - Optionally bake to see the effects.
I had to rename the cache to create the sample file for #74524 (Tooltip for Smoke Simulation Dissolve Time is backwards.)
