Leo, Within your schematic on those components where you want additional control of the ground routing I place a net of GND_Uxx_1 where Uxx is the device and 1 is the pin number. This gives me unique single pin nets. On the pwb you can then route them as you wish and use the virtual short technique (as has been described here). Or as I typically do, I'll route them as I wish and then short them to ground manually which then gives me DRC errors which are easy to recognize as "OK as is" because on the way I've named the nets (i.e. it's OK to short GND_Uxx_1 to GND). I'll then delete those errors from the report (but that's just between you and me). John
