i was wondering is there a way where you can place a block like the one for air but instead of finding all the air but instead it finds all the water connected in that chunk but doesnt remove it from the world instead it just excludes it being added to the schematic for example if you want to make a schematic of a boat but dont wanna copy the water i know you can import a schematic with world edit minus the air i just want something similar but with water

For my own reference, The plan for implementing this is to extend my region blocks to have a configuration screen. It will list all the blocks within a region, and allow you to toggle what will be exported or not. This will save for handing things like lilypads and such.

Oh I see what you mean. Hmn... I can definitely do it, I'm just not sure how to represent it in game.

maybe add a block that acts like area selection like world edit, place a block in opposite corners and it locates the water inside it and excludes it from schematic or even use schematicas selection as it already has a selection tool
