Placing water with #sel fill water

When using "#sel fill water" it requires a water bucket for each water block. For example a line 30 blocks long requires 30 buckets of water. Is there a way to get Baritone to recognize that it only needs two buckets, and can use the infinite water created to fill any area?

For example, when placing a line of water blocks, it could place 2 water buckets 1 tile apart, then use the newly created water to place another in front, and so on.

Would it be possible to achieve this with the current version of Baritone, or could I try creating this feature?
