Config Row-Height for One Row


is it possible to config the row-height for one specific row?
Lets say the first row has a height of 100px and the second a height of 250px?


Unfortunately no, this config sets the height for all tasks.
If you need to change default height only for the first task, you can do it by css. But there is a problem with position of link, because it is displayed according to default task height. Please, check the demo:
