Thanks Benson for your time, I did it through creation of 'fake' section viewports and it worked as proposed by you.
However I think I use this marker tool for things that its probably not intended for...or the tool is not fully developed yet...
The reason is that while I am happy it is shown on VPs as desired, there is no way to control individual floor plan VP and make small changes - move section marker (due to different drawing extent) on one plan but leave it in same position on other. I would love to have control on section marks in individual viewports. At the moment it is same in all VPs.
But thats feature maybe for wishlist.
I did consider to do it second way, but had hope i don't have to place individual section markers and draw every section lines to it... I know you could create new section marker with line and then just pair every two together to get desired result...
