if you like to have feedback out of the community, I would be happy to do so, but I can't read Japanese. Could you maybe also provide your idea in english ?
Project can set parent-child relationship. Suppose, for example, there is a project with parent-child relationship as follows. /Sales management/ / Sales management / Order management / Sales management / order management / Sales management / Inventory management
Despite having a parent-child relationship with all the time, with project filters in various places, Since I want to select the whole sales management, even if I designate a parent, only "/ sales management /" does HIT The child project does not HIT. If you designate a parent, you can improve so that the child will HIT?
I think it's about the project filter, but it needs to be explained further.
