 Dear fellow Electronic humans.  Does someone know if there is the possibility to adjust the soldermask opening for this BGA if I do not have access to the library?  I adjusted the main rule and all other components have been changed, but there is an overwrite for the BGA.  #electronics #altium

 @9e601414 In theory, and I haven't tried this, you can unlock the part, select all the pads and change the solder mask with PCB Filter/PCB Inspector. I'll have a go later when I'm back in front of a computer.
