Bill of Material amendment on ongoing basis

We use bill of materials.
Out problem is that it keeps on growing everyday I.e. Our designer will keep adding content.
However we want to start the MRP asap that the Tortoise BOM is released so that we don’t waste time.

How can we do the BOM edits after submission where we will want to to add items on an ongoing basis and not Impqct the work flows adversely.

The material issue for the project has to happen parallelly and be tracked
