Hi Metin,

> Is there maybe a possible workaround or different approach to get the desired edge loop selection?

Sorry no, not currently. Right now the loop selection mechanism works as described here:

It tries to target a trimming loop on one face. The result you are looking for is crossing over 3 different faces it looks like.
