I suspected so. So this is worse than just a not yet coded feature. 
Unfortunately, doing some portions in advance manually is key to deal 
with many special cases. Examples:

* Make sure, there are proper high current highways

* Do length compensated thin wires for critical timing

* Put down these large heat dissipating copper areas

* Let high voltage lines keep an extra distance to everything else

* Related: Make sure, no track crosses the boundary of the enclosure

Most of my boards have at least one of these cases.
