Hello, You can do what you need by using voids on the inner layers but this is kind of a manual way of doing things.
A better way to handle these grounds is at the schematic level and pass the net information to the PCB editor.
your schematic consider using different grounds "net names" example
gnd, agnd, gnd1, gnd2 etc. The advantage is a plane in the pcb editor
with the same net name will be a "Connect" and planes that do not have
the same net name will have no connection to a via or pin.
From what you write it sounds like all your ground planes have the same net name ? hence the issue.
