Pangaea-like supercontinent - could it have a temperate climate if it has large seas inside?

I have seen from various questions here (and from my research), that a Pangaea-like supercontinent would be very dry, with lots of deserts, since rainclouds couldn't travel a great distance inland.

However, I am pondering the possibility of worldbuilding a Pangaea-like supercontinent with a higher likelihood of temperate, life-favoring environments, by placing seas inland.

The most extreme example I can give is a donut-shaped supercontinent with an ocean at its center.

By bulding on this extreme example, we could gradually fill the central ocean with earth, but maintaining lots of great seas. These seas would be very large and interconnected between themselves, so that they would never dry.

For example, the Black Sea is a large sea connected with the Mediterranean Sea, which in turn is connected with the Atlantic Ocean. Multiply this phenomenum the number of times you wish, in order to create a vast network of large seas and you get the picture of what I'm getting at.

Would this produce the desired effect of creating a supercontinent with more mild climates?

Note: For this question's purposes, let's assume the majority of the landmass is located on equatorial and temperate latitudes, in an Earth-like planet.
