Day separator in unit view

When having multiple units in a week view it’s a bit difficult to see where day changes. Is it possible to make it clearer (like a thicker border) to separate days?

Unfortunately, currently there is no easy way to make border thicker.
Possibly you could change border color with css to black to make it clearer.
For example:

Thanks! That could work. Although I have a “units week view” and then each unit gets a border, not each day. But it’s good to know it’s not natively supported.
