Item List in self-created entity

[LuckyLouie]

Hi
How to add Item List (look Opportunities Layout Manager) to self created entity "Projects"? I add relations beetween Project and Opportunity Item, but field ItemList not exist on Project Layout Manager. I have only entity Project in Layout -> Relations.

Thank You for any help!

This field needs development. Use Item field in Opportunity as example. Start to read from entityDefs. Also we have additional entity OpportunityItem
application/Espo/Modules/Advanced/Resources/metadata/entityDefs/ Opportunity.json and OpportunityItem.json

I created Project.json and ProjectItem.json. I get "error 404. Not found"

"Server side error 404: Layout ProjektyItem:listItem is not found."
