Create a Roll-up Release at the Line level and at the same time create the Sub-Releases automatically with the same Date Range

Today the Date Range fields are not available on the Create Record Layout for Releases. We want to be able to Create a Roll-up Release at the Line level and at the same time create the Sub-Releases automatically with the same Date Range and we can't. We have to create the Roll-up Release, then edit the Roll-up Release to add the Date Range. Then we have to create the Sub-Releases. Having the Date Range fields on the Create Record Layout would make creating a Roll-up Release with many Sub-Releases a one step process instead of a many step process.
