Hi,
at the Austrian Airports we often are commanded by ATC to fly via VFR Sector xyz. (this also includes a maximum Altitude)
There are also VFR Routes to be followed (some oneway, other both directions, again with max. Altitude)
It would be helpful to have that information in the native SD Charts without having to overlay the pdfs.

PS: I never found the coordinates for the sector boundaries, but they are shown on the online VFR chart from austrocontrol.
