Would it be possible to allow the waterfill in blueprints?

Oeh that has been a long time ago that I tried making them blueprintable ... my memory is a bit vague but I think to make this possible I had to make the water pick-upable as well like how you can pick up stone pathing which was kinda weird.

I can when time permits try it again but in all likelihood this is not going to be a thing.

You can blueprint if you create a blueprint with Alt+B (default shortcut), check tiles and then re-update the content of the blueprint with "Select new contents for the blueprint" (the blue button on an opened blueprint). The next time you paste the blueprint, both water tiles and pumps will be pasted in one action. I was using Krastorio 2.
