Hi @sanjay
Currently we don’t support a “continue later” feature when filling up reports. Some people has made the report’s questions (fields) optional, so the user can submit and later edit the report; another option is to split the report into smaller reports, however we understand it’s not always possible.
For a feature like this there are a number of considerations like managing multiple statuses (started, completed, etc), update tasks and targets to trigger and resolve appropriately, etc.
