[kicad-users] Moving parts of a schematic from one sub-sheet to another

[oecherexpat]

Hi guys,
I want to re-organise one of larger schematics which spreads over a
few schematic pages. While I can individually save and re-integrate
whole sheets I can not find a solution to only save and re-load parts
of a sheet like blocks.
Well, that's not completely true: There is a command so save a block.
But how can I get that block loaded back in somewhere???

Thanks, Heiko.
