I work for a high end home builder. We are looking to use Asana as our project manager platform for all the teams required for a project; design, production, interior design and homeowner input. We have a defined process that we are logging into the system. However, as soon as we complete a task, it falls off the project task list. Is there anyway to keep them on the list and show as complete? And, ultimately keep the project “whole” as we do attach photos, material lists, selections and the like.
