Train Numbers 4438XX should be even or 4439XX should be odd

[Shiju 二十七]

The trains 4438XX and 4439XX are both odd, so it could be confusing (for example) train 443835 goes to Dabrowa Gornicza while 443935 goes to Myszkow, but both trains are on same side in the EDR.

Yesterday I had a delayed train 4438XX in Zawiercie GT (left side), so I thought first, it would be the train 4439XX heading to Myszkow...

The problem is that both trains begin with numbers and would swich to even in the middle of their route. We do not have such function as changing train number during a drive, so they both keep their starting parity.
