well yes, but as i understand it, that was before she got her skill but she also hasn't actively tried to use scrolls for house building yet.
maybe if she sees or remembers a japanese house with paper screen walls she will get the idea to use scrolls as wall papers and her skill does the work for her.
besides, she needs to know at least the basics of how to achieve the task for her skill to properly automate it for her. so if she had decided to use scrolls before learning how to create them herself, the skill would either only use the available scrolls or not work for the task at all.
but now that she definitely can make scrolls, her skill should pick up on that and be able to assist her, if she approaches the problem with the right mindset.
afterall, her house building skill is clearly a conceptual skill.
