The adjustment you are looking for is detailed in the VeSys 2.0 Symbol User Guide. Look for "Adding Zone Areas to a Border" in Chaper 7.
After the border you want to adjust is open (in VeSys Symbol), RMB and you will see this:
Adjust the rows and columns as desired, OK, and save.
Hope that helps,
Thank you for your description. It helped a lot. It is very useful that we can change the border (frame, schematic etc.) after we have built the design.
