should I create multiple projects for different chip in one solution?

Dear expert,

After read the difference between solution and project, I still don't understand.

My question is that should I create multiple projects for different chip, like one project for STM32F3 and one for STM32F7 in the same solution?

I did this setup, and found that my STM32F3 project inherit a marco property from solution, which is created by STM32F7 project (I don't know what problem it will cause, just had a bad feeling). So I think I should only group projects for the same target chip under one solution, right?
